Sliding-mode control of power converters: AC/DC converters & DC/AC inverters

ABSTRACT

Sliding-Mode Control (SMC) has been widely utilised to control nonlinear systems with uncertain dynamics. This is due to its order reduction properties, low sensitivity to disturbances, great dynamic performance and ability to reduce the complexity of feedback control design by decoupling the system into independent lower dimensional subsystems. Therefore, significant research has been dedicated to the application of SMC techniques to power electronic equipment and electrical drives. This paper presents a comprehensive control design procedure for AC/DC converters and DC/AC inverters based on SMC. It develops SMC algorithms for several types of power electronic equipment with different control objectives, complete and incomplete information about system states. A wide range of MATLAB/SIMULINK computer simulations are provided to demonstrate the effectiveness of the proposed control design.
