摘要
利用Simulink软件,建立了含二级液压缸的举升系统模型。并对常规的PID控制算法作了相应改进,将改进的PID控制器作为系统的控制环节,对角度信号进行跟踪控制的仿真研究。结果表明,改进的PID控制方法明显减小了跟踪误差,提高了系统的控制精度。
The driven lift system with two stage hydraulic cylinder is proposed using Simulink modules. Improvement has done to conventional PID, and the improved PID controller has designed as the control link of the system, studying of tracking under the control of＂ angle signal has been carried out. Results show that Improved PID control algorithm reduce errors obviously, and enhance the control accuracy.
