So, With our next article we are focusing on Control Systems for GATE Electronics and Communications Engineering aspirants. We will discuss the syllabus, important topics and some good references to study this topic.
Block Diagram reduction technique and equivalent Transfer Functions for both positive and negative feedback are important. Signal Flow Graphs and Mason’s Gain Formula’s help simplify problems here.
2) Time Domain Analysis
Time Response of 2nd Order System, Time Response Specifications and Steady State Error are considered important. Formulas for Rise Time, Maximum Overshoot, Settling Time, Peak Time and also various error coefficients like Position Error Coefficient, Velocity Error Coefficient and Acceleration Error Coefficient are important.
Also,Routh’s Stability Criterion (with it’s special cases) and Root Locus (Complimentary Root Locus) are the important topics.
Formulas of Resonant Frequency, Resonant Peak and Bandwidth should be remembered. Frequency Response and Bode Plots are important.
Gain and Phase Margin.
Model from Transfer Function, Transfer function from State Model, Solution of State Equation, Controllability Observability and Stability of a System are important. Transition Matrix and its relation with Transfer Function should be known.
PD Controller, PI Controller and PID Controller are important.
Lead Compensator, Lag Compensator and Lead-Lag Compensator are important here.
So,If you are on a time crunch it may be a good idea to consider hiring a personal tutor or joining an Online Course to help you save time in understanding of concepts and clearing of doubts. Hence,They should help you analyse your test result and help you get a personalized guidance.
So,While you may take your time to decide for yourself, have a look at a video on Classical Control Theory by one of the faculty at GATE School. Also, At GATE School we provide students with video lectures, personalised mentor support to every student who enrols for the course and ample of tests.
Best of luck for your exam!
