摘要
介绍了四支承液压平台的自动调平原理和方法,提出了液压平台的控制问题。针对平台电液伺服系统高度非线性特性和通道耦合问题,给出了一种模糊自适应控制方案,使控制器的设计不依赖于被控对象精确的数学模型。仿真结果表明:该控制方法响应速度快、控制精度高、鲁棒性好,具有良好的控制效果。
An automatic leveling method for four supports hydraulic platform was introduced and the control problem of it was put forward. Aimed at the problem of high nonlinear dynamics and load coupling among channels for platform electro-hydraulic servo system, a design algorithm based on fuzzy self-adapting control was presented. The controller can be designed without accurate model. Simulated results show that the control approach has high precision, strong robustness against load disturbance and good control performance.
