摘 要:
基于Smith预估控制和参数最优化理论,提出了可变纯滞后时变系统的模型参考自适应预估控制(MRAPC)。MRAPC由自适应预估器,自适应过程模型,自适应机构及常规控制器所组成。它大大地减少了系统中时变参数和可变纯滞后的影响,控制性能明显地强于Smith预估控制。其后给出的仿真结果证实了MRAPC的有效性。
Abstract: Based on Smith Predictor Control and parametric optimization theory, thispaper presents a model reference adaptive predictor control (MRAPC) for time-varying systems with variable time delay. The MRAPC consists of an adaptivepredictor, an adaptive process model, an adaptive mechanism and a conventionalcontroller. It is much better than Smith Predictor Control in reducing the influ-ence of time-varying parameters and variable time delay in the systems. Simulationresults are given to demonstrate the availability of the MRAPC.
