可观测量的电动机驱动电流建模

The mathematical model of the motor drive current based on considerable measure

检验汽车行车制动器设计的优劣,需要得到电动机驱动电流与时间之间的精确关系。因为制动器性能的复杂性,驱动电流与时间之间的精确关系很难得到。基于模拟实验台,由能量等效转化的方法,将能量转化为可观测的转速以及对于转动物体来说恒定不变的转动惯量,建立了电动机驱动电流依赖于可观测量的数学模型。

In order to test the merits of the design on brakes, the precise relationship between the motor drive current and time is necessary. Because of the complexity of the Braking performance, it＇ s too difficult to get the precise relationship. On the basis of Energy Equivalent Conversion, this essay is to get the mathematical model based on the quantities of the motor, such as rotate speed and rotary inertia which is measurable or constant.
