Brushless DC (BLDC) moto r drive based on Freescale’s PowerPC MPC microcontroller. The application design takes advantage of th e Enhanced Time Processing Unit (eTPU) module, which is used as a motor control co-processor. The eTPU completely handles the motor control processing, eliminating the microprocessor overhead for other duties. motor speed and control the motor efficiently. It is also simple to implement and cost effective. The PIC16F7X7 series of microcontrollers have three on-chip hardware PWM modules, making them suitable for 3-phase motor control applications. This application note explains how these microcontrollers can be used for 3-phase AC induction motor control.
In this activity we will design and implement a speed controller for a simple DC motor. In particular, we will choose and tune the gains of a PI controller based on the effect of the gains on the system's closed-loop poles while accounting for the inherent uncertainty in our model. Introduction. Stepping motors are often used as output devices for microprocessor-based control systems. The essential feature of these systems is that the microprocessor program produces a result and the stepping motor must then move the load to the position corresponding to this result.

The following are the functions of a microprocessor in the control of a dc motor fed from a dual converter: Speed sensing: As has already been explained, a digital speed encoder provides the information concerning the speed to a microprocessor.
The train of pulses from the shaft encoder are processed in the microprocessor to estimate the speed. The effectiveness of microprocessor-based systems for realizing digital random logic controllers is illustrated by the design of a controller based on an Microprocessor based motor speed controller.
