摘要
在分析了升降台剪叉机构的运动机理后，提出一种针对精确时变非线性对象的控制方式，改变了以前控制模式中的缺点，使得台面运动姿态得到有效控制，既保证速度均匀稳定，又能更准确地定位．仿真结果表明，该算法简单、实用．
By analyzing the motion mechanism of scissors in lifting platform, a new control algorithm is developed in this paper, which can be used in a class of nonlinear time varying system. With this method, the shortage in classical control method is overcome, and the lifting platform motion mode can be controlled effectively. Not only the speed, but also the position can be controlled perfectly. Simulation results show that the new method is simple and practical for the control problem of lifting platform.
