| 摘 要： | 为了简化位置伺服控制中滑模面的设计,将典型的梯形速度波形设计成指数形式,采用速度和位置两段滑模来代替四段滑模.这样既减少了设计的复杂程度又可应用新的全局滑模和变指数趋近率来提高系统的鲁棒性和消除抖振,并且采用线性化设计、积分消除静差等措施来实现精确的位置定位和速度控制.仿真和实验均证明了该方案对系统参数不确定、外部扰动和噪声具有强鲁棒性.系统的动态、静态品质优良,滑模变结构的抖振也得到了明显抑制,所设计的滑模控制方案是可行和优越的.

| Abstract: | In order to reduce the number of sliding in position servo control,the speed wave is designed in the exponential type instead of the trapezoid type.Meanwhile,the speed and position control with four sliding mode have been replaced by the two sliding mode control.By Introduction of a new global sliding mode and variable exponentially reaching rate,the complexity of the design could be reduced,the robustness of the system would be improved for the eliminated buffeting.By using the linear design and integral m... |
