摘要:
介绍了一种新型的基于数字信号处理器(DSP)的原动机及其调速系统仿真模型,该模型综合了原动机仿真系统数学模型的已有成果,利用TMS320F2812作为控制器,实现完全数字电路控制;采用直流电机加电流、转速双反馈,实现对原动机及其自平衡特性的模拟;通过计算机软件编程实现对调速器的模拟;可将原动机及其调速器仿真系统的运行参数和调节参数以数字信号的形式传输到监控系统或者PC机,操作直观,便于监视。

Abstract:
A simulation model of prime mover and its governor based on DSP(Digital Signal Processor) is introduced,which integrates the proven mathematic models of some prime movers and takes TMS320F2812 as its controller to realize a complete digital control. The prime mover with self-equilibrium characteristic is simulated by DC motor with both speed and current feedbacks while the speed governor is simulated by software. The operating and regulating parameters of simulation system can be sent to the supervisory system or PC for easy operation and intuitive monitoring.
Key words:  prime mover  governor  dynamic simulation  DSP
