Electrical and Computer Engineering

 

316. System Dynamics  

Model formulation techniques for physical systems. Transformation between state-space and classical system representations. Classical solution of LTI system equations. Time and frequency domain solutions of linear state equations. Three lectures. Spring. (Cr. 3)

 

Prerequisite: ELEC 307

 

Goals:

To link physical systems to their lumped parameter representations with emphasis on mechanical, electrical, hydraulic or thermal applications.

 

To review classical linear models based on linear time invariant differential equations, with emphasis on the Laplace transform.

 

To develop the tools of the state-space method using MATLAB, in both its symbolic and numerical form, to do the tedious evaluations.

 

To extend the state-space method to non-linear, time-invariant or time-variant, systems.

 

Objectives:

The student will have developed:

an ability to use modeling tools in the analysis of linear or non-linear, time-invariant or time-variant, systems

an ability to think critically about the modeling of engineering systems

an awareness of the depth of engineering knowledge and the need for life-long learning.

an ability to be a member of a team
