无人机微型舵机伺服控制器及其测试系统的设计

针对高性能的无人机微型舵机伺服控制系统,介绍了一种基于PIC单片机的高精度舵机伺服控制器及其测试系统.通过操纵测试软件,计算机发出模拟飞控计算机发送的位置信号,输入以单片机为主控制芯片的舵机控制器,控制功率驱动电路,驱动直流电机,实现伺服控制.控制器软件采用位置、速度和电流三闭环控制算法,利用模糊比例积分微分(PID)控制算法对位置环进行实时调整,同时在速度环与电流环引入积分分离PI控制算法.实验结果表明,控制器具有抗干扰性好、响应速度快、精度高和输出力矩大等特点.

Design for UAV Micro-servo Controller and Its Test System

To the high performance UAV micro-servo control system,the high accuracy servo controller based on PIC micro-single processor and its test system were introduced.To achieve servo control objective,PIC which was served as main control chip,received position signal from test system,and controlled power driver circuit thus drove DC motor.Three closed loop control strategy with position,velocity and current was adopted in software.Fuzzy PID control algorithm adjusted position loop parameter at real time,and int...
