With the continual growth and increasing model complexities of smart-grid power systems, this work has attempted to design a fractional-order (FO), finite-time non-singular terminal sliding-mode controller (NS-TSMC) to achieve resilient frequency regulatory requirements against stealthy deception (FDI) cyber-attacks and unsteady load demand. The unknown stealthy FDI attacks are estimated employing a FO disturbance observer (FODO). The asymptotic convergence of the estimation error has been confirmed using the Mittag-Leffler stability method. Subsequently, NS-TSMC with estimated FDI attack/plant uncertainties is applied to retain the synchronism of power systems and increase grid resiliency. The exponential stability of the applied control system is studied and presented applying the Lyapunov method. Simulation results performed on Kuntur's two-area four-machine and IEEE 39-bus New-England testbeds have demonstrated proficiency and the disturbance suppression ability of the applied robust cyber-tolerant frequency control framework against stealthy FDI-attack. © 2023 IEEE.

In order to improve the reliability, robustness and cost of the system, the reduction of sensors is an essential component of electric vehicle (EV) drives. In this paper, the speed sensorless control of a synchronous reluctance (SynRL) motor for EVs is presented. For speed estimation, a modified adaptive complex coefficient filter (MACCF) is used. The MACCF reduces the DC offset present in the estimated stator flux linkages, moreover the higher order harmonics in the estimated stator flux are also reduced. The presented filter is also adaptive with speed change whenever the EV is in accelerating and decelerating mode. For effective control of battery parameters and to augment the performance, a bidirectional DC-DC converter (BDDC) is employed with the battery. A SEPIC/ZETA based bi-directional DC-DC converter (S-ZBDDC) is used. The effectiveness of the presented system is validated using MATLAB / Simulink. © 2023 IEEE.

This paper presents a novel hard-thresholding fast iterative filtering (HTFIF) control for a grid-tied solar photovoltaic array (SPVA) system. The effectiveness of this control is tested during grid-connected mode (GCM) in different dynamic conditions like grid outage, variable irradiance, and load unbalancing. A cascaded reduced order generalized integrator orthogonal signal generator (CROGI-OSG) is used as a pre-filter to eliminate the harmonics in grid voltage. The system is designed to operate independently as a Standalone Mode (SAM) when the grid is not accessible. During SAM, a Proportional+Resonant (PR) controller is employed to counteract the oscillatory components in the load voltage. A double frequency and amplitude compensation (DFAC) phase-locked loop (PLL) is used for a smooth transition between GCM and SAM. The effectiveness of the presented control with pre-filter and PLL is evaluated in MATLAB/Simulink environment. © 2023 IEEE.

Along with the development process of intelligentization, graphite spraying technology has been applied in many fields, such as manufacturing, new energy and so on. The amount of graphite powder transported through the powder feeder directly affects the quality of the spraying process, so the optimization study of powder transmission in the powder feeder is very significant. Firstly, a suitable linear regression analysis model was established through the analysis of 21 groups of sample data, having found an optimal match between the powder feeder inlet flow and the motor speed, based on the small number of sampling data in a single set of samples, the grey system GM (1, 1) was selected to establish the prediction model. After verification, the prediction model has high accuracy and effectiveness, which will have certain reference value for future research on powder feeders. © 2023 IEEE.

With a large number of photovoltaic systems connected to the power grid, the harmonic components of medium-voltage distribution network are increasing. In order to reduce the impact of harmonics on distribution network and electrical equipment, it is necessary to study the harmonics generated by photovoltaic generation and the distribution of harmonics in medium-voltage distribution networks. Firstly, the process of photovoltaic generation is introduced. Next, the mechanism of harmonic generation in inverter is analyzed, and the distribution of harmonic in low-voltage distribution network, common connection point and distribution lines are analyzed. Finally, a simulation model is built in MATLAB Simulink environment to simulate and analyze the harmonics of the low-voltage side of the step-up transformer, the common connection point of the photovoltaic generation and the lines of the medium-voltage distribution network. The analysis and simulation results provide the basis for the subsequent improvement scheme and the improvement of relay protection of distribution network. © 2023 IEEE.

This paper presents the first use-case of full second-order Differential Dynamic Programming (DDP) with a whole-body model for model predictive control on legged robot hardware. Recent advances in the literature show that DDP can be simplified by exploiting the dynamics structure in the algorithm, allowing the use of reverse-mode derivative accumulation to efficiently compute dynamics sensitives. These advances allow DDP to be run at similar compute times as the iterative LQR (iLQR) algorithm, its first-order counterpart. Beyond a hardware implementation of these past theoretical developments, this paper provides a characterization of DDP vs. iLQR following push disturbances. One challenge is that DDP often requires regularization to ensure the algorithm improves its control law from iteration to iteration, and an expensive matrix reconditioning is often necessary. We explore a novel methodology to carry out this matrix reconditioning, which considers the local geometry of the cost landscape. The resulting controller is shown to achieve lower costs and withstand larger disturbances as compared to traditional regularization schemes.

With the emergence of more and more automated vehicles, localization of vehicles has attracted a lot of attention. Among multiple localization methods, cooperative localization is very attractive due to its high coverage and accuracy. However, it is costly and leads to larger delays to exhaustively measure and exchange information between all adjacent vehicles. Thus, it is a challenge to schedule the transmissions for the cooperative localization. In this paper, we describe the cooperative localization as a partially observable Markov process and propose an actorcritic deep reinforcement learning algorithm to bring the vehicles to a given localization accuracy threshold as quickly as possible. The proposed algorithm allows the transmissions to be optimally scheduled in a distributed manner. Simulation results show that, compared with random, greedy, and two existing deep reinforcement learning algorithms, the proposed algorithm has better performance and is more adaptable to large-scale complex networks.

The purpose of this paper is to show how to identify and handle suspension system vibrations using two different control strategies: Sliding Mode control (SMC) and a Proportional Integral Derivative (PID) controller. A four-degree-of-freedom (4DOF) half-car suspension model is used. Suspension performance factors such as ride comfort, suspension deflection, and vehicle handling necessitate a thorough control system. This control system, which is carried out with the MATLAB application, is made up of three components: the controller, the suspension system model, and input signals (road profile and actuator force). The simulation results illustrate a comparison between the uncontrolled suspension system and the half-car active suspension system's PID and SMC controllers. © 2023 IEEE.

Different from the traditional permanent magnet motor, the permanent magnet motor for three blade roots vacuum pump (PMM for TBRVP) is difficult to use sensors (or encoders) to achieve multi-motor collaborative control due to its special structure, extreme operating environment and harsh operating reliability requirements;Considering the high failure rate of mechanical structures such as gearboxes, direct drive PMM for TBRVP is becoming mainstream. To this end, a 1.5 kW epoxy resin sealed vacuum pump permanent magnet motor is designed, the key parameters (resistance, inductance, flux, etc.) of a single motor and the non-sensory control system are determined based on the prototype experiment, and then the dual motor collaborative control model is designed, and the deviation coupling multi-motor synchronous control strategy based on the virtual motor is designed. The analysis of four typical working conditions shows that the maximum rotor position following error between the motors is 2.29 degrees (far lower than the critical value of 5 degrees), and has good anti-interference ability.
