# IC6501 CONTROL SYSTEMS MCQS 2013 REGULATION

In this post we have posted some notes on IC6501 CONTROL SYSTEMS  for ANNA UNIVERSITY AFFILIATED COLLEGES STUDENTS.
Here We have listed the the notes whichever we could collect for IC6501 CONTROL SYSTEMS  subject, We think that it will be helpful for your exam preparation.

### OBJECTIVES:

• To understand the use of transfer function models for analysis physical systems and introduce the control system components
• To provide adequate knowledge in the time response of systems and steady state error analysis.
• To accord basic knowledge in obtaining the open loop and closed–loop frequency responses of systems.
• To introduce stability analysis and design of compensators
• To introduce state variable representation of physical systems and study the effect of state feedback

#### UNIT I SYSTEMS AND THEIR REPRESENTATION

Basic elements in control systems – Open and closed loop systems – Electrical analogy of mechanical and thermal systems – Transfer function – Synchros – AC and DC servomotors – Block diagram reduction techniques – Signal flow graphs.

#### UNIT II TIME RESPONSE

Time response – Time domain specifications – Types of test input – I and II order system response – Error coefficients – Generalized error series – Steady state error – Root locus construction- Effects of P, PI, PID modes of feedback control –Time response analysis.

#### UNIT III FREQUENCY RESPONSE

Frequency response – Bode plot – Polar plot – Determination of closed loop response from open loop response – Correlation between frequency domain and time domain specifications- Effect of Lag, lead and lag-lead compensation on frequency response- Analysis.

#### UNIT IV STABILITY AND COMPENSATOR DESIGN

Characteristics equation – Routh Hurwitz criterion – Nyquist stability criterion- Performance criteria – Lag, lead and lag-lead networks – Lag/Lead compensator design using bode plots.

#### UNIT V STATE VARIABLE ANALYSIS

Concept of state variables – State models for linear and time invariant Systems – Solution of state and output equation in controllable canonical form – Concepts of controllability and observability – Effect of state feedback.

### OUTCOMES:

Ability to understand and apply basic science, circuit theory, theory control theory Signal processing and apply them to electrical engineering problems.
