This project aims to control the speed of a permanent magnet DC motor using a cascade control technique. The project explores the operation of a PMDC motor, an H-bridge using a unipolar switching scheme, and PI controllers in both the current loop and speed loop of the cascade control. It investigates the practical implementation of cascade control on a PMDC motor using a flexible inverter board. The project also examines the effect of anti-windup C code on drive performance.
The project begins with an introduction to the hardware and software used, including the DC motor test rig, flexible inverter board, RL load, dsPIC30F3010 microcontroller, in-circuit debugger unit, MPLAB X IDE, LABVIEW, and MATLAB. The project then delves into the background theory of PMDC motors, H-bridges, and cascade speed control, including the mathematical model of the PMDC motor, its electrical and mechanical characteristics, and MATLAB simulations. It also discusses the four-quadrant operation of DC motors, the current loop, speed loop, optical encoders, and ADC conversion. The project then examines the control of the H-bridge's Leg A and Leg B, including the role of the gate driver IC IR2130. It concludes with experimental results for the control of the H-bridge, unipolar PWM switching, current control, speed control, and the inner and outer speed loops.
The project focuses on keywords such as cascade control, PMDC motor, H-bridge, unipolar switching, PI controller, current loop, speed loop, flexible inverter board, dsPIC30F3010 microcontroller, anti-windup C code, and drive performance.
It is a control strategy using an inner current loop and an outer speed loop to regulate the motor's performance more effectively.
An H-bridge allows voltage to be applied in either direction across a motor, enabling it to run forwards or backwards.
It is a switching scheme for the H-bridge that reduces ripple in the armature current compared to bipolar switching.
Anti-windup prevents the integral term of the PI controller from accumulating a large error when the output is saturated, improving drive recovery.
The project implemented the control on a dsPIC30F3010 microcontroller using C code.
