Module Details

Have  a  good  understanding  of  how  to  calculate  and  analyze dynamic behavior of physical systems, including fundamental notions of dynamics like stability and transfer function.

Use and simplify block diagrams

Construct  and  interpret  Bode  diagrams  and  root  locus diagrams

Understand the significance of controller actions (proportional, integral, derivative).

Apply methods of optimal tuning of PID controllers

 

There are no prerequisite modules. Students should have some basic knowledge of differential equations and mass and energy balances

ections of first order systems. Second-order systems. Time delay systems.

MATHEMATICAL METHODS FOR THE ANALYSIS OF

DYNAMIC SYSTEMS. Solution of linear vector differential equations with the exponential matrix method. Asymptotic stability of linear systems.Solution of linear differential

equations using Laplace transforms. Transfer function. Poles and zeros. Input/output stability. Frequency response calculation. Bode diagrams. Linearization of nonlinear dynamic systems. Local asymptotic stability –Lyapunov’s first method

FEEDBACK CONTROL SYSTEMS. Measuring devices. Final Control Elements. Controllers with proportional, integral and/or derivative actions (PID). Block diagram representation of a control system. Block diagram simplification. Closed loop transfer functions. State-space description of a closed loop system.

ANALYSIS AND DESIGN OF CONTROL SYSTEMS. Steady state error -significance of integral action. Sensitivity function. Closed loop stability analysis. Routh stability criterion. Bode stability criterion.
