ResumoA new method for the sliding surface design of variable structure control systems (VSS) using frequency criteria of H∞ theory is presented in this paper. H∞ theory is a well-known tool for forming desired frequency character in linear controller designs. We show that an H∞ state feedback solution is available for sliding plane design. The idea of augmented control plants, where the system states are increased by appropriate frequency weights, is also useful for sliding mode control. With this approach, frequency shaping which agrees with the specification of the response can be designed.
