Catalog Description:

Prerequisite: ENT341, ENT342, ENT302, and Senior Standing

Study of s-domain techniques for open-loop and closed-loop systems with emphasis on stability and performance. Classical methods of control engineering are presented: Laplace transforms; transfer functions; root-locus analysis; Routh-Hurwitz stability analysis; steady-state error for standard test signals; and second-order system approximations. Computer tools, MATLAB and Octave, are introduced and utilized extensively for computer aided analysis and design. Laboratory exercises provide practical application of control-system theory. Individual computer-managed homework exercises insure student competency. Required for electrical engineering technology majors.

Reason for revision:

Revision of course content reflects recent electrical engineering technology developments and current trends.
