Objective :
In this course it is aimed to introduce to the students the principles and applications of control systems in every day life. The basic concepts of block diagram reduction, time domain analysis solutions to time invariant systems and also deals with the different aspects of stability analysis of systems in frequency domain and time

Concepts of Control Systems- Open Loop and closed loop control systems and their differences- Different examples of control systems- Classification of control systems, Feed-Back Characteristics, Effects of feedback. Mathematical models – Differential equations, Impulse Response and transfer functions - Translational and Rotational mechanical systems

Transfer Function of DC Servo motor - AC Servo motor- Synchro transmitter and Receiver, Block diagram representation of systems considering electrical systems as examples -Block diagram algebra – Representation by Signal flow graph - Reduction using mason’s gain formula.

Standard test signals - Time response of first order systems – Characteristic Equation of Feedback control systems, Transient response of second order systems - Time domain specifications – Steady state response - Steady state errors and error constants – Effects of proportional derivative, proportional integral systems.

The concept of stability – Routh’s stability criterion – qualitative stability and conditional stability – limitations of
Routh’s stability
Root Locus Technique:
The root locus concept - construction of root loci-effects of adding poles and zeros to G(s)H(s) on the root loci.

Introduction, Frequency domain specifications-Bode diagrams-Determination of Frequency domain specifications and transfer function from the Bode Diagram-Phase margin and Gain margin-Stability Analysis from Bode Plots.

Polar Plots, Nyquist Plots Stability Analysis.

Compensation techniques – Lag, Lead, Lead-Lag Controllers design in frequency Domain, PID Controllers.

State Space Analysis of Continuous Systems
Concepts of state, state variables and state model, derivation of state models from block diagrams, Diagonalization- Solving the Time invariant state Equations- State Transition Matrix and it’s Properties – Concepts of Controllability and Observability

  1. Testimony on how i got my LOAN from ...

    I'm Isabella Tyson from 1910 N Halsted St Unit 3, Chicago IL60614 USA,, i have been searching for a genuine loan company for the past few months and all i got was bunch of scams who made me to trust them and at the end of the day took my money without giving anything in return, all hope was lost i got confused and frustrated, i find it very difficult to feed my family and vowed never to have anything to do with loan companies on net and went to seek of assistance from a very good friend which i explained all my experience regarding online companies with and said he can help me that he knows of a Godsent and well known company called FUNDING CIRCLE PLC, he stated he just got a loan from them although i was still very unsure about this company due to my past experience but i decided to give it a try and did as i was directed by my friend and applied, i never believed but i tried and to my greatest surprise i received my loan in my bank account within 24 hours, i could not believe that i would stand on my feet financially again. I’m glad I took the risk and applied for the loan and today i'm thanking God that such loan companies still exist and promise to share the good news to people who are in need of financial assistance because the rate of scams on net is getting very serious and i don't want people to fall victim when we still have genuine and Godsent lenders.. You can contact this Godsent company using the information as stated and be a partaker of this great testimony.. Email: OR Call/Text +14067326622 thanks


    Life indeed is GRACE, I'am Daan Sophia currently in California USA. I would like to share my experience with you guys on how I got a loan of $185,000.00 USD to clear my bank draft and start up a new business. It all started when i lost my home and belongings due to the bank draft I took to offset some bills and some personal needs. I became so desperate and began to seek for funds at all means. Luckily for me I heard a colleague of mine talking about this company, I got interested although i was scared of being scammed, I was compelled by my situation and had no choice than to seek advise from my friend regarding this very company and was given their contact number, getting intouch with them really made me skeptical due to my past experience with online lenders, little did i know this very Company "PROGRESSIVE LOAN INC. was a godsent to me and my family and the entire Internet World, this company has been of great help to me and some of my colleague and today am a proud owner of well organized business and responsibilities are well handled all thanks to Josef Lewis of ( So if really you are genuinely in need of a loan either to expand or start up your own business or in any form of financial difficulty, i advise you give Mr Josef Lewis of Progressive loan the opportunity of financial upliftment in your life Email: OR Call/Text +1(603) 786-7565 and not fall victim of online scam in the name of getting a loan. thanks
