| Abstract: | Based on the Volterra series representation of nonlinear transfer function matrix, the stability of closed loop control systems for a class of MIMO discrete nonlinear control systems is discussed, and the new method for judging FDBIBO (BIBO stability in frequency domain) stability for the closed loop control system by using its open loop subsystem stability is proposed in this paper, and its validity is demonstrated by a simulation example. |
