本文着重讨论十六位微机控制的电液随动系统的设计与实现。数字控制器设计综合了Bang-Bang控制与积分分离PID控制的设计思想,微机根据系统误差角大小适时地变更数字控制器的结构——控制算法。该方法对具有大惯性负载的位置随动系统,实现快速、高精度、平稳跟踪等项技术要求很有实际意义。文末给出的实时采集系统的阶跃响应表明,该设计方法可取得较好的控制效果。 This article focuses on the design and implementation of sixteen microcomputer-controlled electro-hydraulic servo system. The design of the digital controller integrates the design idea of ​​Bang-Bang control and integral separation PID control, and the microcomputer changes the structure-control algorithm of the digital controller according to the system error angle. The method is of great practical significance to the technical requirements of the follow-up system with large inertia load, to achieve fast, high-precision and smooth tracking. The step response of the real-time acquisition system given at the end of this paper shows that this design method can achieve better control effect.
