BULLETIN OF THE POLISH ACADEMY OF SCIENCES-TECHNICAL SCIENCES 2017年第1期65卷 3-9页

作者： Wan, Y. Nanjing Univ Aeronaut & Astronaut Coll Automat Engn Nanjing 211106 Jiangsu Peoples R China

In this paper, a new control scheme is proposed to achieve stability for a single-machine infinite-bus power system. A power system model simultaneously considering input saturation and time-varying uncertainties is presented. A sufficient condition for the system convergence is given and based on this result, a switching excitation control law with auxiliary system is designed. The stability analysis and simulation results all show that the developed controller is effective.

A nonlinear robust controller design procedure is presented, which is designed to simultaneously satisfy multiple conflicting closed-loop performance specifications. Significantly, a robust performance specification for the experimental system, developed for studying the attitude control of a small-scale helicopter in our previous work, is discussed quantitatively. The robust performance specifications and nominal multiple closed-loop performance specifications are conflicting. Use of the Convex Integrated Design (CID) method can provide, where feasible, a single closed-loop controller which satisfies a set of multiple conflicting performance specifications. However, the resultant controller has a complex form. Here, the standard CID method is extended to a more general control system framework to solve the conflicting simultaneous performance design problem. When compared with the standard CID design, the extended CID design procedure generates a relatively simple closed-loop controller. Finally, the synthesised controller is tested in simulation and is validated with an experimental small-scale test helicopter, demonstrating the performance of the proposed controller.

nonlinear robust control of Unknown Robot Manipulator Systems With Actuators and Disturbances Using System Identification and Integral Sliding Mode Disturbance Observer

In this study, nonlinear robust control of robot manipulator systems with completely unknown manipulator dynamics using a system identification and integral sliding mode disturbance observer (SI-ISMDOB)-based sliding mode control (SMC) method is proposed. Because the unknown robot manipulator system-owing to the actuator dynamics, unknown manipulator parameters, frictional forces, and unknown load torques-cannot be controlled using the existing model-based methods, they need to be identified;subsequently, the identified manipulator system should be controlled in a robust manner. To this end, the manipulator-actuator dynamics at the motor shaft are first proposed by considering the unknown robot manipulator dynamics as torque disturbances and are subsequently identified using the system identification. An SI-ISMDOB-based SMC method is then developed using the identified manipulator-actuator dynamics and torque-disturbance estimates from the ISMDOB. The simulation and experimental results on an actual planar manipulator system are presented to verify the improved performance of the proposed method over the SMC method and SMDOB-based SMC method via a performance indicator.

In this paper, the technique of model reference robust control (MRRC) is applied to a passive line-of-sight (LOS) stabilization system. The system uses a flywheel as a spining mass gyroscope to stabilize a two gimbal system against base motion. Due to the gimbal geometry, unwanted dynamic coupling exists in the LOS system. The system is treated as a two input - two output system, and it is then decoupled and controlled using only input/output measurements rather than state feedback. The technique used in this paper for decoupling and control of the LOS system is MRRC which is an extension of model reference control to nonlinear MIMO systems. The technique utilizes bounds of plant parameter uncertainties via controller parameter uncertainties and also input disturbances bounds. Specifically, dynamics of the passive line-of-sight stabilization system are described, followed by a perfect knowledge (MRC) control design and then a nonlinear robust control design.

In this article, a nonlinear robust（NR） control is designed for static synchronous series compensator（SSSC） to improve transient stability and oscillation damping of power system. By taking the parameter deviations, external disturbances and unmodeled dynamics into account, the nonlinear dynamic model of SSSC can be changed into a Hamiltonian structure with the help of coordinate transformation. Based on the Hamiltonian structure of SSSC, a nonlinear robust control is designed for SSSC. Numerical simulation results on the two-area four-machine power system demonstrate the robustness and effectiveness of the proposed nonlinear robust control in comparison with the direct feedback linearization（FL） control. The study results show that the nonlinear robust control has better performance than the FL control.

To solve the trajectory tracking control problem of underwater vehicle-manipulator system (UVMS) under strong nonlinear couplings and complex parametric uncertainties and unknown external disturbance, a nonlinear robust control method based on time delay estimation (TDE) was proposed and investigated in this paper. The core idea of this method is that builds the basic architecture of the controller with TDE, and realizes the online estimation and real time compensation of the complex unknown lumped dynamics for the system. Afterwards, a designed desired dynamic equation is used to regulate the system control performance. Benefitting from the compensation of the unknown lumped dynamics and the model-free nature of TDE, the proposed method has good robustness and practical easy usage. Finally, the effective of the proposed method was demonstrated by comparative numerical simulations with a 9 degree of freedoms (DOFs) UVMS.

A practical nonlinear robust control approach of electro-hydraulic load simulator

作者： Wang Chengwen Jiao Zongxia Wu Shuai Shang Yaoxing School of Automation Science and Electrical Engineering Science and Technology on Aircraft Control Laboratory

This paper studies a nonlinear robust control algorithm of the electro-hydraulic load simulator （EHLS）. The tracking performance of the EHLS is mainly limited by the actuator＇s motion disturbance, flow nonlinearity, and friction, etc. The developed controller is developed based on the nonlinear motion loading model. The problems of the actuator＇s disturbance and flow nonlinearity are considered. To address the friction problem, the friction model of the loading motor is identified experimentally. The friction disturbance is compensated using the obtained friction model. Therefore, this paper considers the main three factors comprehensively. The developed algorithm is easy to apply since the controller can be obtained just with one step back-stepping design. The stability of the developed algorithm is proven via Lyapunov analysis. Both co-simulation and experiments are performed to verify the effectiveness of this method.

This paper presents a new approach and corresponding experiments for the nonlinear robust control of a superconducting magnetic energy storage (SMES) unit to improve the transient stability of power systems. Based on the result of SMES prototype experience, a new dynamic model with disturbances of SMES is adopted, and transferred to the per unit system for simplifying the dynamic analysis and controller design. Then, feedback linearization scheme and linear H-infinity control theory are applied to design a novel SMES nonlinear robust controller in a one-machine infinite bus (OMIB) power system. In order to confirm such positive effects of the proposed control strategy, experiments are carried on a laboratory setup of SMES comparing that with a conventional proportional-integral (PI) controller. The results of experiments demonstrate that the proposed nonlinear robust controller has more excellent performance to improve the transient stability of power systems than that of conventional PI controllers.
