【Abstract】 The adaptive control problem of a class of SISO nonlinear control systems is studied, which can be modeled by a finite discrete Volterra series model. Firstly, the parameters are estimated by using the recursive least_square method, then the control law is presented by solving a polynomial equation. The local convergent property of the proposed algorithm is proved by the local stability theory of feedback Volterra systems. Simulation results corroborate the proposed algorithm.更多还原
