摘　　要：设计了一个基于虚拟仪器和Proteus的直流电机转速控制仿真系统,对比研究了Bang-Bang控制和PID控制两种控制方式对直流电机转速控制的影响。该仿真系统分为上位机、下位机两部分:上位机完成对实时转速的显示和监测,并通过串口向下位机发送控制指令和给定转速,下位机根据控制命令完成对直流电机的转速控制,并将电机实际转速发送给上位机。在此基础上,完成了下位机硬件实验系统的设计与实现。实践证明,该仿真系统有助于学生深入理解计算机控制系统的理论,培养学生自主学习和解决复杂工程问题的能力。Based on virtual instrument and Proteus,a set of DC motor speed control simulation system is designed,and the effects of Bang-Bang and PID control on DC motor speed control are compared.The system is divided into host computer and slave computer.The host computer completes the display and monitoring of the real-time speed,and sends the control commands and the given speed to the slave computer through the serial port.The slave computer completes the speed control of the DC motor according to the control commands,and sends the actual speed to the host computer.The hardware experiment system of the slave computer are also completed.Practice has proved that the simulation system helps students to master the theory and practice of computer control system,and cultivate students'ability of autonomous learning and solving complex engineering problems.
