DC Motor H-bridge: Sign/Magnitude Control – Multibody, Multi-Domain Physical Model in MapleSim – Maplesoft

DC Motor H-bridge: Sign/Magnitude Control

This model represents a DC Motor with a PID speed controller associated with other subsystems that are necessary in the real life: a constant voltage source feeding an H-bridge controlled by PWM signals, and the logic to create this signals from the output of the PID controller. This type of logic is called “sign/magnitude” because you need to define the PWM duty cycle and the direction of the motor in order to create the PWM signals.

This model was created with MapleSim 2022.2
