Special Issue Information

Dear Colleagues,

The robust control of electrical machines have achieved rapid development and been widely used in many applications, such as in assistance, manufacturing, electric vehicles, renewable energy applications, etc. The types of electrical machines include synchronous machines, permanent-magnet machines, interior permanent-magnet synchronous machines, synchronous reluctance machine, permanent-magnet flux-switching machines, linear machines, induction machines, permanent-magnet vernier machines, etc. The rapid development of the market has put forward higher requirements for robust control of these machines. Over the past few decades, there have been numerous advancements in the robust control schemes like sliding mode control, model predictive control, intelligent control, adaptive control, etc. However, several new challenges still exist which require innovative techniques and solutions. The adaptiveness and autonomy of sliding mode controllers are not fully exploited in the current industrial systems. Therefore, we are seeking more advanced sliding mode control approaches to promote the applications of machines in industry and academia.

The main objective of this Special Issue is to bring together researchers from both the academia and industry areas to present recent advancements and challenges in the field of sliding mode control for electrical machines in various applications using artificial intelligence algorithms like artificial neural networks, fuzzy control theory and deep reinforcement learning methods, model predictive control algorithms, , adaptive control methods, high order control methods and other composite control structures.

This Special Issue is meant to cover topics related to mathematical modeling, machine learning, artificial intelligence, optimization, and numerical methods aiming at improving the performance of both integer and fractional order sliding mode control schemes for electrical machines.

The induction motor (IM) drives are prone to various uncertainties, disturbances, and non-linear dynamics. A high-performance control system is essential in the outer loop to guarantee the accurate convergence of speed and torque to the required value. Super-twisting sliding mode control (ST-SMC) and fractional-order calculus have been widely used to enhance the sliding mode control (SMC) performance for IM drives. This paper combines the ST-SMC and fractional-order calculus attributes to propose a novel super-twisting fractional-order sliding mode control (ST-FOSMC) for the outer loop speed control of the model predictive torque control (MPTC)-based IM drive system. The MPTC of the IM drive requires some additional sensors for speed control. This paper also presents a novel machine learning-based Gaussian Process Regression (GPR) framework to estimate the speed of IM. The GPR model is trained using the voltage and current dataset obtained from the simulation of a three-phase MPTC based IM drive system. The performance of the GPR-based ST-FOSMC MPTC drive system is evaluated using various test cases, namely (a) electric fault incorporation, (b) parameter perturbation, and (c) load torque variations in Matlab/Simulink environment. The stability of ST-FOSMC is validated using a fractional-order Lyapunov function. The proposed control and estimation strategy provides effective and improved performance with minimal error compared to the conventional proportional integral (PI) and SMC strategies. Full article
