ECE 3714 Introduction to Control Systems | ECE | Virginia Tech

Undergraduate PROGRAMS

Course Information


Introduction to the design of feedback compensation to improve the transient and steady-state performance of systems. Emphasis is on modeling, analysis and analog compensator design for single-input single-output systems. Modeling techniques, root locus analysis and design, the Nyquist criterion, and frequency domain compensation.

Why take this course?

Improving the performance of systems using feedback control is a fundamental aspect of almost all high-performance systems, from electronic circuits to autonomous vehicles. This course will introduce students to the basic concepts of feedback control and provide the necessary background and understanding required for more advanced courses in controls.

Learning Objectives

  • model and simulate controlled systems in continuous time
  • analyze feedback systems using root locus and frequency domain techniques
  • design compensators to improve the transient and steady-state performance of the closed-loop system while maintaining stability
