摘要：

伺服压力机是目前成形装备发展的一个新方向。为了提高其位置控制的响应特性，针对其非线性、时变性、滞后性，提出了基于模糊算法和PID算法的模糊PID控制器，在C++ Builder中开发模糊PID控制器以实现PID参数的在线修正。阶跃响应和正弦跟随的实验结果表明，所设计的模糊PID控制器能够有效的提高响应速度、降低超调量和稳态误差，并且具有较强的抗干扰能力。模糊PID控制器拥有比传统PID控制器更好的控制效果，可以有效的提高伺服压力机位置控制性能。

Servo press is a new developing trend in forming equipment. Aiming at the nonlinearity, time-variability and time lag existing in servo system, the fuzzy PID control method was applied to conduct the position servo press control system. A fuzzy PID controller was built up to achieve the PID parameter setting of regulator using the Borland C++ Builder. The experimental results of step response and sinusoidal signal response show that this method could effectively raise the response speed，reduce overshoot and steady-state errors, and have powerful ability of restraining external disturbance. The control algorithm using fuzzy PID control has the better performance than that of traditional PID control algorithm, which is an effective method to improve servo presss position control.
