摘要：

A strategy for time-delayed feedback controloptimization of quasi linear systems with random excitationis proposed. First, the stochastic averaging method isused to reduce the dimension of the state space and to derivethe stationary response of the system. Secondly, the controllaw is assumed to be velocity feedback control with timedelay and the unknown control gains are determined by theperformance indices. The response of the controlled systemis predicted through solving the Fokker-Plank-Kolmogorovequation associated with the averaged It? equation. Finally,numerical examples are used to illustrate the proposed controlmethod, and the numerical results are confirmed byMonte Carlo simulation.
