Digital Controls

Catalog description

This course builds on the fundamentals of continuous feedback control to introduce the student to computer (digital) regulation of systems in closed-loop. Discrete-time modeling of signals and systems is discussed. Analog and digital control schemes are compared using s domain to z-domain conversion, and time-domain response characterization. Closed-loop system design objective specification and evaluation is conducted through numerical simulation. Various discrete-time controller designs are implemented. Topics for the class include: continuous to digital control conversion using finite difference solutions; continuous to digital control conversion using state equation approach; stability of discrete systems; PID control design for digital systems; frequency domain control system design methods for continuous systems (PID, lead, lag, lead-lag compensation design); frequency domain control system design methods for digital systems (PID, lead, lag, lead-lag compensation design) using phase loss methods and bilinear transformation; z-transforms for discrete systems; digital control system design using root locus ; and deadbeat control design. Students will be required to do computer projects using Matlab and program Arduinos. There will be two exams and several homework assignments
