Courses 2025

ENME462                  Vibration, Controls, and Optimization II

Course Description       Continuation of ENME361. Fundamentals of vibration, controls, and optimization. Analysis and design in time, Laplace and frequency domains. Mathematical descriptions of system response, system stability, control and optimization. Optimal design of mechanical systems.

ENME662                  Advanced Linear Vibrations

Course Description:  Development of equations governing small oscillations and spatially continuous systems. Newton's equations, Hamilton's principle, and Lagrange's equations. Free and forced vibrations of mechanical systems. Modal analysis. Finite element discretization and reductions of continuous systems. Numerical methods. Random vibrations.

ENME489P/808P      Control of Smart Structures

Course Description:  ENME 489P/808P introduces the theory and practice of control systems engineering of smart structures. These structures consist of an integration of mechanical systems with arrays of piezoelectric sensors and actuators.  Control of these smart systems is becoming an integral part of modern society that found applications in a broad range of critical systems such as robots, car suspensions, and spacecraft. In this course, students will learn how to describe systems mathematically using Lagrange’s dynamics and analyze those multi-filed descriptions both in the time and frequency domains. This course includes integrated virtual experiments that allow students to master the MATLAB, SIMULINK, and LABVIEW engineering computing environment.
