| 摘要: |
| 随着雷达探测技术的发展，传统PID算法存在对控制增益敏感、“快速性”和“超调性”不可调和以及微分很难选取等缺点，已不能满足雷达伺服系统对控制性能的要求。自抗扰控制(ADRC)具有不依赖被控对象模型、无超调、响应速度快、鲁棒性强的优点，越来越受到重视，但其缺点是参数众多、调节过程复杂。线性自抗扰控制器(LADRC)通过对自抗扰控制算法线性简化和参数整合，极大简化其参数和调节过程，同时又保持了自抗扰控制的优点。将线性自抗扰控制器应用到雷达伺服系统以提高其响应快速性和鲁棒性，减小系统的超调性。最后对比传统PID控制器，试验结果表明，线性自抗扰控制器在提高雷达伺服系统响应速度、稳定性、抗干扰和鲁棒性方面优于PID。 |

| Abstract: |
| With the development of radar detection technology, due to the disadvantages such as sensitive to control gain, the contradiction “fast” and “overshoot”, and difficult to choose differential, the traditional PID control algorithm cannot satisfy the control performance requirements for radar servo system. ADRC is more and more attention for its independent on models, non-windup, fast response and robustness. However, it has too many parameters and is difficult to be adjusted. So the linear auto disturbance rejection controller(LADRC) is established by means of linear simplification and parameter conformity, the adjustment of parameters is simple obviously. LADRC is adopted to further improve response and robustness and reduce overshoot for servo system. Finally, compared with the PID controller, experimental results show that the LADRC is better in improving radar servo system response, stability precision, anti-disturbance and robustness. |
