Sliding modes in power electronics and motion control systems

In this paper the concepts, design aspects and application of Sliding Mode Control (SMC) systems to power electronics and motion control systems are discussed. The salient features of the Variable Structure Systems (VSS) with sliding modes are order reduction, decoupling in the design procedure, insensitivity in plant parameter changes and disturbances rejection. Simple implementation makes concepts of SMC very attractive in power electronics and motion control systems. Application to problems like control of DC and AC converters, the control of electrical machines and the design of the observers for electrical machines are discussed.
