Abstract: Two structures connection have the characteristic of imprecise model and are subjected to stochastic outside force. In the paper, on the control method choice hand, the generalized predictive control, which has better control effect on imprecise model, is adopted to ensure the realization of system control successfully. On the optimum objects choice hand, in order to reduce control system energy, the Frobenius norm of the control matrix is chosen as optimum objects of system control, On the optimum algorithm choice hand, in order to abbreviate the calculation work, an improved genetic algorithm is used to seek the optimum solutions of control matrix. All sub-optimum solutions required can be provided for designers. In the last, a numerical example is presented to show the effectiveness of the method.
