-To use Matlab to verify and simulate control systems.

-To write project report.  

Course Objectives:

Students should be able to  

-Understand characteristics of feedback control systems.

-Find mathematical model of physical systems in transfer function form.

-Describe quantitatively transient response of first- and second-order systems.

-Approximate higher-order systems as first or second order system.

-Design system parameters to meet transient response specifications.

-Find steady-state error of feedback system.

-Design controller to meet steady-state error performance specifications.

-Determine stability of a system by means of Routh-Hurwitz criterion.

-Sketch a root-locus.

-Use root locus to describe qualitatively changes in transient response and stability of a system as a system parameter is varied.

-Use root locus to select a system parameter to meet transient response specifications.

-Use root locus to design compensators to improve transient and/or steady-state error.

-Plot frequency response.

-Use frequency response to analyze stability and transient and steady-state error performance of a system.

-Use frequency response to design gain to meet stability and transient response specifications.

-Use frequency response techniques to design compensators to improve transient and/or steady-state error.

-Use Matlab to verify and simulate control systems.

-Design simple control systems.

-Write project report.
