【Abstract】 This paper deals with a kind of nonlinear systems with the piecewise linearization method based on the theory of Hyperstability. A model reference adaptive control law is derived to ensure the stability of the system. According to the result of simulation by means of Matlab, we have confidence that the problem can be well solved by this method.更多还原
