control of CascadedBrushless Doubly-Fed Induction Motors With Real-Time Torque Optimization

IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS 2023年第11期70卷 11098-11108页

作者： Hossain, Md Abid Bodson, Marc Univ Utah ECE Dept Salt Lake City UT 84108 USA

Brushless doubly-fed induction machines offer a potential alternative to regular doubly-fed induction generators for wind turbines, due to higher reliability and lower maintenance costs. As motors and generators, the brushless machines could also be part of new technological solutions for hybrid-electric propulsion, including aircraft propulsion. The main advantage is that most of the power would be transferred from generators to motors without electronic conversion. The article proposes a new speed control algorithm that maximizes the available torque within the limits of the control winding currents and ensures anti-windup protection. The maximum torque and the control variables are obtained through simple analytical computations. The derivations of the article are based on a complex-variable representation that simplifies the mathematical model and the control algorithm. Compact formulas specify the controller parameters as functions of the machine parameters and the desired closed-loop behavior. The results are tested on a laboratory testbed using a cascaded doubly-fed induction motor and demonstrate fast responses reaching torque limits that are computed in real time by the algorithm. While control is achieved through the converter interfaced with the control windings, the data shows that most of the active and reactive power is exchanged directly through the power windings. Similar results are obtained in simulations of a larger brushless doubly-fed induction motor.

This paper presents an improved sensorless control of a Salient-Pole Permanent Magnet Synchronous Machine (SPMSM) based on fuzzy logic model reference adaptive system. For this purpose, an observer based on a model reference adaptive system is utilized and the respective analytical model is established to receive the speed and the position of the rotor. To accurately determine the rotor position, the fuzzy logic method is adopted, and the control coefficients of the model reference are determined online based on the governing rules of the control system. The presented method is simulated via MATLAB/SIMULINK software. The simulation results confirm that the presented model can successfully improve the accuracy of tracking rotor position in a shorter time frame.

In the motor drive system fed by multilevel inverter, the problems such as the complexity of reference voltage synthesis, high common mode voltage (CMV), and high switching loss are usually the obstacles to the practical application. In order to reduce the computational complexity and improve the performance of permanent magnet synchronous motor (PMSM), a novel space vector pulsewidth modulation scheme, which is practical and independent of level number is proposed for PMSM vector control. First, the space vector plane is redivided, and the coordinates of the nearest three vectors and their duty cycles can be obtained directly by determining the location of reference vector, which simplifies the calculation and does not need any iterative algorithm. Then, the optimal switching state and switching sequence are selected online so as to ensure the minimum switching loss under the premise of minimum CMV. This article provides an original method and new idea for motor drive system fed by multilevel inverter. Finally, the practicability and validity of the proposed method are verified by simulation and experiment.

In order to realize the high performance and miniaturization design of the servo drive, this paper designs a 3kW servo drive based on the wide band gap SiC MOSFT. Based on the analysis of the mechanism of crosstalk, a SiC MOSFET driving circuit with active clamp to suppress crosstalk of the bridge arms is designed, the servo drive system uses field-oriented vector control algorithm to drive the motor. The servo drive system is built with TMS320F28379D as the core controller and 17-bit absolute encoder as the position sensor.

We usually find applications of rotary induction generator, direct-drive tubular linear permanent-magnet generator, etc. for the mechanoelectrical conversion process within Stirling microcogenerator systems. This paper presents the design optimization investigation for a direct-drive tubular linear induction generator for a dual free-piston Stirling microcogenerator system. On the one hand, a high oscillating frequency and a relatively long piston's travel bring about a very high acceleration of the generator's moving part, up to 1018 m/s(2). On the other hand, the tubular linear induction generator offers many interesting assets in this application: low weight mover, appearance of levitation force, no mechanical spring, low mechanical losses, no cogging force, easy manufacture, very low investment and maintenance cost, and so on. However, the tubular linear induction generator is sparsely used, because of its a priori relatively low energetic efficiency. This paper presents a sizing optimization approach for maximizing the performance and demonstrates that, with an astute arrangement of electrical devices, the tubular linear induction generator can constitute a well adapted solution for free-piston Stirling microcogenerator systems.

field-programmable Gate Array Based Fuzzy Sliding-mode controller for a Permanent Magnet Synchronous Motor Drive

ELECTRIC POWER COMPONENTS AND SYSTEMS 2014年第13期42卷 1440-1451页

In this article, a field-programmable gate array based fuzzy sliding-mode controller is proposed to control a permanent magnet synchronous motor drive. First, the dynamics of a permanent magnet synchronous motor is derived, and the vector control scheme is introduced in the current loop. Next, to improve the performance of the permanent magnet synchronous motor drive, a fuzzy sliding-mode controller with an integral-operation switching surface is proposed and applied to the speed loop, in which a fuzzy inference mechanism is adopted to generate the reaching control signal. Further, an integrated hardware design method is developed to implement the field-oriented vector current controller and the proposed fuzzy sliding-mode speed controller on a single field programmable gate array chip. Finally, a prototyping platform based on an Altera field-programmable gate array is established to evaluate the ability of the proposed fully integrated solution in terms of control quality and time/area performances. The preferable performance of the proposed field-programmable gate array-based fuzzy sliding-mode control approach for permanent magnet synchronous motor drive is verified by the experimental results compared with the conventional proportional-integral control and sliding mode control schemes.

Multiphase drives are receiving attention not only for medium and high power applications, but also for some low power applications, such as heavy electric vehicles. In the case of multiphase induction machines, the most widely adopted control technique is the field -oriented vector control, which provides high torque dynamics and can exploits all the degrees of freedom that this technology offers, but requires an adequate knowledge of the machine parameters. In this paper, a technique for the on-line estimation of the stator resistance and the magnetizing inductances is proposed. Under the assumption that the machine torque is produced by the fundamental component of the air -gap magnetic field, the proposed technique controls the higher harmonics in such a way to excite the machine and to estimate the unknown parameters. Experimental tests confirm the feasibility of the method described in the paper.

Using equidistant vector-based hysteresis current regulators in DFIG wind generation systems

ELECTRIC POWER SYSTEMS RESEARCH 2011年第5期81卷 1151-1160页

作者： Mohseni, Mansour Islam, Syed Masoum, Mohammad A. S. Curtin Univ Technol Dept Elect & Comp Engn Perth WA Australia

This paper proposes a novel equidistant vector-based hysteresis current regulator (VBHCR) in the rotorside converter (RSC) of DFIG-based wind generation systems. The Gamma-form equivalent circuit is used for the machine modelling, with the discrete formulation of the RSC output voltage. The overall vector control scheme is then explored and the control structure of the proposed equidistant VBHCR is presented. When compared to the commonly used PI current regulators, the proposed VBHCR exhibits several advantages such as very fast transient response, simple hardware implementation, satisfactory steady-state performance, and intrinsic robustness to machine parameters variations. Moreover, fixed hysteresis bands are replaced with equidistant bands in order to limit the instantaneous variations of the switching frequency and reduce the maximum switching frequency of the RSC. Detailed simulation studies are carried out for a 1.5 MW DFIG-based wind generator to examine the operation of the proposed current regulator under various operating conditions and demonstrate its superiority over the standard PI current regulator.

This paper presents a robust speed control method for a permanent magnet synchronous motor (PMSM) drive. The controller designed from conventional field-oriented vector control method with constant parameters will result in an unsatisfactory performance of a PMSM due to dynamic uncertainties such as changes in load and inertia. In this paper an adaptive self-tuning (ST) observer that estimates dynamic uncertainties on-line has been developed, where output is fed forward as compensation to the PIVISM torque. The stability of the observer is studied using the discrete-time Lyapunov theory. A performance comparison of the proposed controller with the constant parameter based conventional field-oriented vector controller is presented though a simulation study, which illustrates the robustness of the proposed controller for PMSMs.

A multiloop feedback control system supplemented by a complementary controller is used to improve the drive performance of an AC induction servo motor and reduce sensitivity to parameter variations, nonlinear effects, and load disturbances. Based on the principle of field-oriented vector control, a software-based current-decoupled controller has been proposed. A simplified model of the current-decoupled induction motor has been used for the design and simulation of the proposed robust controller. Experimental results based on multimicroprocessor implementation are presented to illustrate improved response and reduced sensitivity.
