摘　　要：介绍了一种新型的数模混合控制型原动机仿真系统.该系统综合了原动机仿真系统数学模型已有的成果,对系统中的调速器、电流调节器等,采用灵活的计算机软件去实现其功能,触发电路由TC787集成块完成,不仅使硬件线路大为简化,且使整个系统的控制精度、可靠性和稳定性等大幅度提高.测试结果表明,系统能很好地实现对原型电动机各特性的仿真,而且与传统的设计方案相比,具有明显的优势.A new prime mover simulation system is introduced, which is controlled by digital and simulative circuits and integrates the mathematic models of some prime movers.The functions of governor and current adjustor in the system are realized by flexible computer sofeware,which greatly simplifies the hardware circuits and improves the precision,reliability and stability. Static and dynamic experiments show that the introduced system can well simulate the characteristics of prime movers. It is obviously prior to the systems designed with analog circuits.
