基于Simulink的火炮伺服系统自抗扰控制仿真

摘要

An active disturbance rejection control (ADRC) technology is proposed for an artillery servo system with load disturbance and large disturbed moment. It is to be used in the location controller in the artillery servo system. The control method made up insufficient of the traditional control method by real-time estimation and compensation. Three-loop model(speed loop, location loop and current loop)of artillery servo system with closed-loop ADRC was established in the Simulink software. It was compared with the traditional PID mode control method. The simulation results show the system based on ADRC technology has the advantages of high-speed response,less overshoot and strong robustness.%为了解决火炮伺服系统存在负载变化大、冲击扰动力矩强等问题，将自抗扰控制技术应用到火炮伺服系统位置控制器中。该控制算法通过实时估计与补偿来弥补传统控制方法的不足。通过在Simulink软件平台搭建了ADRC的火炮伺服系统三环模型，仿真结果对比传统PID控制。对比结果表明，基于ADRC的系统超调小、响应速度较快、具有较强的鲁棒性。
