CONTROL SYSTEMSPosted by Ekeeda on February 28th, 2019 If I’m asked what is a ‘control system’, I would say a control system is a system which consists of a number of components combined together to perform a specific function in which output is controlled by the input. A control system manages, commands direct, or regulates the behaviour of other devices or systems using control loops. Introduction to Control systems Control is applied to alter the operation of a system so it works in a specific beneficial way over time. For example, we may want the speed of a car on the highway to remain as close as possible to 60 km per hour in spite of speed breakers or we may want an aircraft to follow the desired altitude etc. All these are being achieved today by control techniques and the above are instances of what automatic control systems are created to do, without human interference. Control is applied whenever measures such as temperature, voltage, altitude, or speed must be made to behave in some desirable way over time. Control systems can be of two types based on their characteristic components - a) Open loop systems Control systems will help one understand the concepts like Time Response Analysis, Root Locus Technique, Frequency Response Analysis, State Space Analysis etc. Ekeeda offers great online courses for budding physicists. Our course structure is comprehensive and following are the chapters of our Control systems course.
One learns about the concept of a transfer function of a linear, time-invariant system which is the ratio of the Laplace transform of the output to the Laplace transform of the corresponding input with all initial conditions assumed to be zero.
This chapter will enable us to understand how to create block diagrams and their equivalent signal flow diagrams. One also learns about their usage in engineering, hardware design, electronic design, software design etc.
Mathematical models of physical means are the bases of control theory. In this section, we will study the three distinct mathematical models namely, linear ordinary differential equation, state variable or state space description, and transfer function.
In this chapter, we will focus on understanding the various elements of a control system and their utility in the control system circuits. This includes learning about- a) Condition to be controlled b) Sensor c) Comparator d) Activator
This chapter focusses on analysing the response of the control system. We will learn to plot the output of the control system when input varies with respect to time and thus called the time response of the control system.
We will learn about stable control systems and the necessary condition under which a control system behaves like a stability control system, which is following The Routh’s Hurwitz Criterion, a form of mathematical test.
This chapter will teach you to perform a graphical procedure for determining the poles of a closed-loop system given the poles and zeros of a forward-loop system.
This chapter revolves around how the amplitude and phase shift change with the frequency of the input perturbation.
In this chapter, we will study to put the physical system as a collection of input, output and state variables related by first-order differential equations or difference equations as a mathematical model. 10.Elementary Idea of Compensating Networks & Controllers This chapter will enable us to develop a basic idea behind compensating and controlling an unstable system to make it stable. We will learn to apply Compensating networks to the system in the form of feed forward path gain adjustment. The industry veterans were the mind behind creating these amazing and detailed chapters on Control systems. For further details or queries, you can reach out to us anytime.
