Design of Fuzzy PID Cascade Control for Radar Stabilization Platform and Simulation

摘要:

机载雷达稳定平台是根据陀螺仪采集到载机角速度信息，驱动直流伺服电机采用反向运动补偿原理工作，以保证机载雷达成像稳定，清晰。为了提高机载雷达稳定平台的响应性能和抗干扰能力，提出一种模糊PID串级控制方案，根据陀螺仪所采集的角速度信息和编码器反馈的角度位置信息，采用速度模糊PID控制和位置模糊PID控制串联的形式对直流伺服电机进行控制。经MATLAB仿真实验证明，模糊PID串级控制比传统单级PID控制以及传统PID串级控制具有更优秀的响应性能以及抗干扰能力，更加适合复杂环境下机载雷达稳定平台的稳定要求。

Abstract:

The airborne radar stabilization platform is based on the angular velocity information collected by the gyroscope, and the DC servo motor is driven by the reverse motion compensation principle to ensure stable and clear imaging of the airborne radar. In order to improve the response performance and anti-interference ability of the airborne radar stability platform, a fuzzy PID cascade control scheme is proposed. According to the angular velocity information collected by the gyro encoder and the angular position information of the encoder feedback, the speed fuzzy PID control and The position fuzzy PID control is connected in series to control the DC servo motor. The MATLAB simulation experiment proves that the fuzzy PID cascade control has better response performance and anti-interference ability than the traditional single-stage PID control and the traditional PID cascade control, and is more suitable for the stability requirements of the airborne radar stabilization platform in complex environments.
