| 摘 要： | 针对某火箭炮位置伺服系统参数变化范围大，冲击力矩强等特点，提出了一种全局滑模控制方法，并结合伺服系统数学模型对其进行了稳定性证明，同时对于控制律中的高阶微分项，引入微分估计器来获取其高精度估计值。仿真结果表明，该控制方法不仅能够有效抑制抖振，保证系统的响应速度和控制精度，并且对参数摄动和负载扰动具有很强的鲁棒性。

| Abstract: | Aimed at wide parameter variations and strong impact moment in a rocket launcher position servo system,a global sliding mode control method was presented.Its stability was proved by using the system’s mathematic model.And,for the high-order derivative term in the control law,a derivative estimator was introduced to obtain the high accuracy estimation.The simulation results show that the proposed approach can inhibit the chattering problem effectively,guarantee the response speed and control accuracy,and possess a strong robustness to parameter perturbation and load disturbance. |
