摘要
针对某地面雷达要求设备体积小、拆装方便、重量轻等特点,系统以单片机PIC18F2431为核心,以无刷直流电动机为伺服电机,提出软件伺服策略,构成全数字高精度伺服系统。考虑系统机械谐振、力矩耦合及电气参数波动等非线性不确定因素的影响,采用模糊规则和改进型抗积分饱和相结合的PID控制器。实验结果表明,该系统控制精度高、响应速度快,对体积和重量有严格限制的小型天线伺服系统的设计有重要参考价值。
A ground-based radar device requires small size, easy accessibility, light weight and other characteristics. By using PIC18F2431 as the core controller, brushless DC motor as servo motor, the software servo strategy was proposed and the all-digital high-precision servo system was constituted. Considering mechanical resonance,torque coupling and elec- trical parameters fluctuations nonlinear uncertainties, a PID controller combining fuzzy rules and improved anti-reset windup was used. The experimental results show that the system has high precision, fast response, and has reference value to the small antenna servo system design with strict limits on the volume and weight.
