Continuous approximation of variable structure control. (English) Zbl 0599.93029

Variable structure control systems with linear plant and switching hyperplanes are considered. In order to avoid chattering, the authors propose a continuous control law which approximates perfect sliding motion obtained by the discontinuous one. This extends to the multivariable case some results of G. Ambrosino, G. Celentano and F. Garofalo [Int. J. Control 39, 1339-1349 (1984; Zbl 0534.93035)]. An example is presented.
