A common actuator in control systems is the DC motor. It directly provides rotary motion and, coupled with wheels or drums and cables, can provide translational motion. The electric equivalent circuit of the armature and the free-body diagram of the …

The DC Motor block allows you to model two types of faults: Armature winding fault — The armature winding fails and goes open circuit. Field winding fault — The field winding that creates the magnetic field fails and goes open circuit.

Build and Simulate a Simple DC Motor. In this example, you model a DC motor driven by a constant input signal that approximates a pulse-width modulated signal and look at the current and rotational motion at the motor output.

Figure 1: Equivalent circuit for a DC electric motor. 1.1.1 Resistance model The resistance R of the motor is assumed to be constant. 1.1.2 Torque model The shaft torque Qm is assumed proportional to the current i via the torque constant K Q, minus a friction-related current io. Qm(i) = (i −io)/K Q (1) 1.1.3 Voltage model

DC motors work by generating opposing magnetic fields that produce a force (or torque) on the shaft. The change in “opposition” is created by changing the set of coils that are magnetized (powered) in the armature through the split commutator. Input could be voltage or current.

A common actuator in control systems is the DC motor. It directly provides rotary motion and, coupled with wheels or drums and cables, can provide translational motion. The electric circuit of the armature and the free-body diagram of the rotor are shown in the following figure:

In order to use the DC-motor in the simulations, mathematical modelling has to be done, in order to yield the relations between the current, voltage and rotational speed. Here I will show how to setup model of a…

3 天之前 · 在Simulink中，电动机的仿真建模通常涉及电气、机械和控制系统的建模。以下是一个基于Simulink的直流电动机（DC Motor）仿真建模实例，包括具体的建模步骤和代码实现。 1. 直流电动机模型. 直流电动机的数学模型可以表示为：

From the DC Motor Speed: Simulink Modeling page we generated two different DC motor models in Simulink. We will now employ these models within Simulink to simulate the system response and design different approaches to control. A linear model of the system can be extracted from the Simulink model into the MATLAB workspace.
