A variable structure system (VSS) differs from a tradition automatic control system in that its structure is purposefully changed, in Jump-wise fasion, during the transient process, depending on the current values of the error signal and its derivatives. Introduced in this paper is the principle of design and analysis of VSS; and several essential advantages, such as high speed, insentiveness to variations in plant parameters and external disturbances, and simplicity of physical realization are pointed...
