摘要
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 paper presents the principle and the structure of a 16-bit computer(TWS-0600) controlled high precision electro -hybraulic position servo system. The major study of the authors is on design and implemention of the controller. Combing the idea of PD-PID control and Bang-Bang control, the structure of the controller varies with the system error depending on the logic decision of computer. The expriment results show that the design is effective for electrohydraulic servo system with large inertial load to meet the demand of high speed, high precision and smooth tracking in low speed. The step response recorded by the way of real time data acquisition gives the satisfactory control results.
