摘要
传统的Smith预估器较好地解决了前向通道大滞后系统的控制问题,但对于反馈通道中传感器延迟造成的滞后的问题则并不适用。提出了一种改进的Smith预估控制方法,克服了反馈通道中大滞后对于控制系统稳定性的不利影响。仿真结果表明:该方法能够有效地抵消前向通道与反馈通道同时存在的大滞后环节对控制系统稳定性的负面影响。
Traditional Smith predictor solves control problem of forward path big time lag system, but not suitable for the systems contain pure time-delay in feedback path. Put forward an improved Smith predictive control method which overcome negative influence of large delay feedback path on stability of control system. Results of simulation show that this method can effectively set-off negative influence of large delay co-existed in forward path and feedback path on stability of control system has remarkable positive effect on control processes.
