Description: 无刷直流电机控制系统的研究与实现
简单介绍了无刷直流电动机的工作原理，分析并确定了主回路的导通方式，控制器一是以专用芯片MC33035来进行设计，位置反馈元件有霍尔传感器反馈接口和编码器接口，开关器件采用MOSFET管，设计有转速反馈闭环控制、正反转、过电流保护等。控制器还采用89C52单片机、 MAX7219、AD667等来实现数字转速给定和转速显示。控制器二是基于PICSF4431电动机控制专用芯片，采用全数字PID控制，有转速、电流双反馈，位置反馈采用编码器反馈，开关器件采用IGBT，在PWM输出端有GAL芯片保护，防止上下桥臂直通。在控制器二中，备有两套程序，程序一是没有进行外加给定值采样，采用两两PWM全导通方式，在此情况下，电机的转矩波动明显，程序二中采用PWM导通方式，电机的转矩波动较小，运行性能较好。
-Brushless dc motor control system of research and implementation
Brushless dc briefly introduced the working principle, analysis and the main circuit conduction mode, the controller is a MC33035 special-purpose chip to design, position feedback components have hall-effect sensor feedback interface and encoder interface, switching device adopts MOSFET, design speed feedback loop control, positive &negative, over current protection, etc. Controller still through 89C52 and MAX7219, AD667 etc to achieve rotational speed and digital display is given. Controller based on PICSF4431 motor control is the special chip, using digital PID control, speed and the current double feedback, position feedback using encoder feedback, switching device IGBT power output terminals are in PWM GAL chip protection against fluctuation bridge at arm. In the second, with two sets of controller, a program is not given by sampling, plus the value of all pairwise PWM conduction mode, in this case, the motor torque Platform: |
