摘要
结合原动机仿真系统数学模型的已有成果,设计了基于TMS320LF2407A的原动机及其调速系统模拟装置。利用灵活的计算机软件实现了系统中的调速器、电流调节器和触发器的功能,实现了控制部分的全数字化,不仅使硬件线路大为简化,而且大幅提高了整个系统的控制精度、可靠性和稳定性等。动、静态测试试验表明该系统不仅能很好地实现对原型调速器及原动机自平衡特性的仿真,而且与模拟电路的设计方案相比,其具有明显的优势。
Integrating the mathematic models of some prime movers, a prime mover and the governor simulation equipment based on TMS320LF2407A is designed. The function of governor, current adjustor and trigger in the system are realized with flexible computer software, to implement wholly digital control that greatly simplify the hardware circuits and improve the precision, reliability and stability. Static and dynamic experiments show that, the introduced equipment can well simulate the prime governor and the self-equilibrium characteristics of prime mover and it is obviously prior to the systems designed with analog circuits.
