Where can open loop control be used?
Discussion: Open loop control can be used in systems where motor velocity is not critical, and where accurate positioning is not necessary. Open loop control can also be used with stepper motors to control their position, provided they are properly sized for the load. Topic: What is meant by open loop vs. closed loop? Discussion: Open loop is control without feedback. Closed loop control compares motor current, velocity, or position feedback with a desired value and generates a modified command to make the error smaller. Topic: What is the difference between Microchip’s motor control family vs. standard MCU devices? Discussion: Most of Microchip’s MCU devices can be used to control a motor, but the motor control MCU family has peripherals which are designed to simplify the implementations of controlling various types of motors. Current peripherals offered are I/O ports driven via firmware to turn on/off, sequence, or generate PWM signal to the motor, CCP’s, ECCP’s, & 3-Phase PWM module
