摘　　要：文章针对自动机械变速器试验台使用发动机存在成本高、安装复杂以及受负载限制而出现发动机运转不平稳等问题,设计了一种基于变频器的电机调速系统来代替发动机作为AMT试验台的动力源,并介绍了AMT试验台以及电机的调速原理,详细阐述了电机调速系统的设计方案。系统采用虚拟油门模拟油门踏板作为驾驶员意图的输入来控制电机,实现了调速系统与AMT控制单元之间的CAN通讯以及电机实时调速功能,并建立了自适应PID控制器,从而对电机的转速进行精确控制,实验结果表明电机调速系统能够满足AMT试验台的使用要求。Aiming at solving problems like high cost, complex installation and unstable running because of loads restriction in the engine in used automatic mechmaical transmission（AMT） test-bench, a motor speed control system based on frequency converter is designed to replace engine as the power source of AMT test- bench. The principles of the AMT test-bench and the speed regulation of motor are introduced, and the de- sign scheme for the motor speed control system is elaborated. The system uses virtual accelerator to simulate the accelerator pedal as the input of the driver＇s intent to control the motor, and functions such as the CAN- BUS communication between the speed control system and AMT control unit and the real-time motor speed control are achieved. And a self-adaptive PID controller is established, thus accomplishing the precise control of the motor speeck The experiments are done to verify the system, and the results show that the motor speed control system meets the requirements of the AMT test-bench.
