摘要
变结构模型跟踪控制系统既具有由稳定性方法设计的一般模型跟踪控制的自适应性,又具有变结构滑模控制的优点。但在具体实现时,由于控制滞后等因素会引起震颤,从而影响系统的正常工作。设计了一种受生物启发的变结构模型跟踪控制算法,其设计简单,参数调整容易。仿真结果表明,该控制优于一般的变结构模型跟踪控制,不仅能有效抑制震颤,而且能改善系统跟踪性能,并能减小非自衡对象加载后的静差,全面改善了系统的动态、静态性能。
Variable structure model-following control system has not only the feature of a model-following control system, but also the advantages of a variable structure system. But when it is implemented, the chattering caused by the control delay will make the system work abnormally. A biologically inspired variable s structure model-following control algorithm is proposed, which is simple in design and easy to regulate the parameters. It is shown from the simulation results that the control is superior to the conventional variable structure model-following control. It can not only depress the chattering effectively, but also improve the dynamic performances, and reduce the static errors of the controlled object after the object is loaded.
