摘　　要：针对扑翼飞行器气动性能试验对风洞流场的实际需求,以PLC和变频器为主要硬件平台,设计了一种由转速环和风速环组成的串级控制系统,并引入转速前馈控制以提高系统响应快速性;通过对转速环和风速环控制调节器以及转速前馈函数进行合理的设计,实现了良好的流场控制效果;试验结果表明,风扇电机转速稳态精度优于0.2%,试验段稳态风速精度优于0.2 m/s,风洞流场调节过程平稳、抗扰动性能好,现已成功在风洞中开展扑翼飞行器气动性能试验。A flow field control system is designed to meet the requirement of aerodynamic performance test for the flapping wing aircraft.Based on the hardware of PLC and converter,a cascade control system composed of a motor speed loop and a wind speed loop is given.And in order to improve the fast response,the motor speed feedforwad method is proposed.Due to the reasonable control regulator and feedforward function,the flow field control has achieved a good result.The test results show that the precision of motor speed is superior to 0.2%,the precision of wind speed is superior to 0.2m/s,the system has smooth adjustment process and good disturbance rejection.The system has been applied successfully to the aerodynamic performance test for the flapping wing aircraft.
