摘要
为了克服电动负载中惯量机械模拟方法的固有缺点,研究了惯量电模拟及其实现方法。在分析惯量电模拟原理的基础上,提出了基于Luenberger观测器的加速度估计方法。为了验证实现方法的有效性,以双闭环直流调速系统作为被试验对象,采用与机械模拟相比较的方法,分别模拟不同的负载惯量,分析了突加给定工况的动态调节过程,结果表明本文提出的惯量电模拟方法是可行和合理的。
In order to overcome the inherent shortcomings of inertia mechanical emulation in electrical load,realization of inertia electrical emulation was researched.The principle of inertia electrical emulation was analyzed,and then an acceleration estimate method based on the Luenberger observer was proposed.Double close-loop direct current speed regulate system was selected as the test object to verify the effectiveness of the realization approach.The dynamical response process of step reference was analyzed and compared with mechanical emulation method under the different load inertia.The simulation results indicated that the inertia electrical emulation method was feasible and reasonable.
