PID(比例积分和微分)控制很难使具有本质非线性和时变特性的电液伺服系统达到较高的控制性能.仿人智能控制则是在PID控制原理基础上,结合人对运动物体的控制经验而进行控制的一种智能控制方法.这种控制方法可以避免一般PID控制中存在的快速性、稳定性和高精度控制作用的相互抵制,能够有效地按人的意志对系统实施连续的三段控制:加速起动,超调制动和稳定消差.实验证实了仿人智能控制电液伺服系统的优越性.
PID (Proportional Integral and Derivative) control is hard to make the electro-hydraulic servo system with intrinsic nonlinearity and time-varying characteristics achieve high control performance. Humanoid intelligent control is based on the PID control principle, combined with the human on the moving object Control experience and control of a kind of intelligent control method.This control method can avoid the general PID control exist in the rapidity, stability and high-precision control of the role of the mutual boycott can effectively implement the system of continuous Three-stage control: accelerating start-up, overshoot braking and steady-state eliminating error.The experiment proves the superiority of humanoid intelligent control electrohydraulic servo system.
