摘要
对单自由度时滞系统主动控制的最优控制方法和变结构控制方法进行了研究,给出了反馈增益的稳定性条件和最大时滞量的解析确定方法,并采用移相技术进行时滞补偿.算例结果显示,移相技术能够较好地对系统中的时滞进行补偿,时滞补偿变结构控制方法的控制效果优于时滞补偿最优控制方法.
Optimal control method and variable structure control method were applied for active control of single-degree-of-freedom system with time delay. The stability condition for control feedback and maximum allowable time delay were investigated. The phase shift technique was used to compensate time delay. The simulation results indicate that time delay may be effectively compensated by using the phase shift technique. With time delay compensated, the control performance of variable structure control method is much superior to that of optimal control method.
