摘　　要：以某型飞行器主桨的变桨距控制系统为研究背景,设计了一套位置伺服控制系统。为进行高精度的位置控制,保证变桨距机构平稳且快速的作动效果,以DSP和CPLD为核心架构进行了硬件电路设计;并根据变桨距作动装置的主要参数进行控制系统建模,运用PID控制方法实现电机控制,进行了控制律设计、仿真分析和软件编写。实验结果表明:系统位置控制的带宽不低于5 Hz,稳态误差在10%以内,变桨距作动装置的运动速度不低于20 mm/s,桨距角改变速度不低于28(°)/s,系统的控制精度高和稳定性好,能够满足应用需求。Based on the research background of an aircraft main propeller variable pitch control system,this paper designs a position servo control system.In order to be able to perform high-precision position control,thus to ensure the smooth and fast operating effect of the variable pitch mechanism,the hardware circuit was designed based on DSP and CPLD.The simulation model was modeled according to the main parameters of the variable pitch actuator.The PID control method is used to realize motor control,and the control law design,simulation analysis and software programming were carried out.The experiment shows that the bandwidth of system position control is not less than 5 Hz,the steady-state error is within 10%,the motion velocity of variable pitch actuator is not less than 20 mm/s,and the speed of pitch Angle change is not less than 28(°)/s.The system has high control accuracy and good stability,which can meet the application requirements.
