EC1304 CONTROL SYSTEMS 3 1 0 100
AIM
To familiarize the students with concepts related to the operation analysis and stabilization of control systems
OBJECTIVES
• To understand the open loop and closed loop (feedback ) systems
• To understand time domain and frequency domain analysis of control systems required for stability analysis.
• To understand the compensation technique that can be used to stabilize control systems
UNIT I CONTROL SYSTEM MODELLING 9
System concept, differential equations and transfer functions. Modelling of electric systems, translational and rotational mechanical systems, Simple electromechanical systems.
Block diagram representation of systems – Block diagram reduction methods – Closed loop transfer function, determination of signal flow graph. Mason’s gain formula – Examples.
UNIT II TIME DOMAIN ANALYSIS 9
Test signals – time response of first order and second order systems – time domain specifications – types and order of systems – generalised error co-efficients – steady state errors – concepts of stability – Routh-Hurwitz stability – root locus.
UNIT III FREQUENCY DOMAIN ANALYSIS 9
Introduction – correlation between time and frequency response – stability analysis using Bode plots, Polar plots, Nichols chart and Nyquist stability criterion – Gain margin – phase margin.
UNIT IV COMPENSATORS 9
Realization of basic compensators – cascade compensation in time domain and frequency domain and feedback compensation – design of lag, lead, lag-lead compensator using Bode plot and Root locus. Introduction to P, PI and PID controllers.
UNIT V CONTROL SYSTEM COMPONENTS AND APPLICATION OF CONTROL SYSTEMS 9
Stepper motors – AC servo motor – DC servo motor – Synchros – sensors and encoders – DC tacho generator – AC tacho generator – Hydraulic controller – Pneumatic controller – Typical application of control system in industry.
