【摘要】 时滞导致控制力的不同步实施,不仅降低控制系统的性能,而且会使动力系统不稳定。针对这个实际问题,本文对时滞补偿及时滞对控制系统的影响进行了研究。控制律采用现代最优控制方法设计,采用移项法补偿时间滞后。数值结果表明,所提控制方法能够较好地控制系统的峰值响应,而且能够保证控制系统的稳定性。更多还原

【Abstract】 Time-delay causes unsynchronized application of control forces that may not only degrade the performance of the control system but also even induce instability to the dynamics system. In view of this practical problem, a time-delay compensating control algorithm is studied in this paper. Accordingly, effects of the time-delay on control system are studied. A semi-active control algorithm based on the theory of modern optimal control is illustrated and the method for compensating time delay, i.e. phase compensation method is given. Simulation results demonstrate that the presented time-delay compensating control algorithm is effective in reducing maximum responses of the systems and the system stability can be guaranteed by using this control method.更多还原
