【Abstract】 In this paper, a new method is proposed for the determination of weighting matrices in linear optimal control design by means of optimization technique. Under the given preliminary permissible overshoot of each state variable dynamic response, the linear optimal control law can be obtained with the algorithm presented by computer automatically.The method proposed has been applied to design the optimal excitation control of a long d is-tance power transmission system and obtained the law of optimal excitation control .Based on this control law, the stability limit of power system would be close to the power limit of the transmission line. Computer results have shown that the method proposed in this paper is simple and convenient, and especially suitable for the design of linear control systems for higher requirement at dynamic response.更多还原
