Course Description

Covers electronic control systems, open-loop and closed-loop, proportional, integral, derivative, PI, and PID control modes, power control devices, relays, transistors, thyristors, and sensors. Topics include temperature control, DC motor control, and stepper motor control. Lab exercises include temperature control and motor control circuits. Audit available.

Addendum to Course Description

Students will measure the operating characteristics and performance of power control devices and feedback control systems in the associated laboratory.

Intended Outcomes for the course

Upon successful completion students must be able to:

1. Operate and troubleshoot open loop and closed loop control systems.
2. Use transfer functions to predict the correct operation of control systems.
3. Measure and evaluate the performance of basic open loop and closed loop control systems.
4. Operate and troubleshoot switch mode power supplies, converters, and motor drives.

Course Activities and Design

Concepts and theories presented in class are demonstrated in the laboratory. Lab experiments are synchronized with the lectures.

Outcome Assessment Strategies

Assessment methods may include midterm and final exams, homework, lab evaluations, and projects.
