Where can an open loop control be used?
Open loop can be used on systems where motor velocity is not critical, and where accurate positioning is not necessary. Applications such as fan and blower control, pump control, and some low-end home appliances are examples. What is meant by open loop vs. closed loop? Open loop is control without feedback. Closed loop control compares velocity or position feedback with the commanded velocity or position and generates a modified command to make the error smaller. The error is the difference between the required speed and the actual speed. What is the difference between Microchip’s motor control microcontrollers vs. standard microcontrollers? Microchip’s motor control microcontrollers have 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, Capture/Compare/PWM, Enhanced Capture/Compare/PWM, & 3-Phase PWM modules t
