Design of Servomechanisms Using Sliding Mode and Quasi-Sliding Mode
Transactions of the Institute of Systems, Control and Information Engineers, 1988 A method for designing a servomechanism using sliding mode is considered. This servomechanism of which the input-output relation is given by a transfer function is insensitive with respect to disturbances, parameter variations, and nonlinearity. The structure of this servomechanism satisfies the internal model principle. A servo-mechanism is also given
