中文说明：这个例子是类似于连续的版本，但离散化允许更快的仿真。 电路描述： 直流电机是美联储通过直流电源通过一把菜刀 GTO 晶闸管和一个宽松自由的二极管组成。 电机驱动机械负荷惯性 J、 磨擦系数 B，和负载转矩热释光特征。电机采用离散的直流电机，机械库中提供。
English Description：
This example is similar to the continuous version, but discretization allows faster simulation. Circuit Description: A DC motor is fed by a DC source through a chopper which consists of GTO thyristor and a free-wheeling diode. The motor drives a mechanical load characterized by inertia J, friction coeficient B, and load torque TL. The motor uses the discrete DC machine provided in the Machines library.
