摘要
对时滞线性系统的瞬时最优控制方法进行了研究 ,并给出控制具体实现过程。由于控制律是直接通过时滞微分方程而得出 ,因此该方法易于保证控制系统的稳定性 ,且具有普遍适用性。算例结果显示 ,所提控制方法能够较好地控制系统的峰值响应 ;若按无时滞控制设计对时滞系统进行振动控制 。
Instantaneous optimal control method for linear systems with time delay in control is investigated in this paper.Since the optimal controller is obstained directly from time delay differential equation,system performance and stability are prone to be guaranteed.And this control method is generally avilable for ordinary control systems with time delay.Simulation results demonstrate that the presented control method is effective in reducing maximum responses of structures.Instability in responses occurs possibly if the systems with time delay are controlled by a controller that is designed without time delay.
