Eddy Current DefinitionAccording to Lenz’s law, when a conducting loop is exposed to a changing magnetic field, it generates an emf that induces a current opposing the change. Similarly, when a magnetic field changes through a conducting body, like a filament or a slab, it causes currents to flow through the material’s cross-sections.These currents are given the name eddy currents after the water eddies that are small swirling whirlpools observed in lakes and oceans. These eddy current loops can

Routh Hurwitz Stability Criterion DefinitionIt is a method to determine the stability of a system using the characteristic equation.Hurwitz CriterionUsing the characteristic equation, we can create several Hurwitz determinants to determine the system’s stability. The characteristic equation of the system is defined as follows:There are n determinants for an nth order characteristic equation.Here is how to write determinants from the coefficients of the characteristic equation. Follow these steps

Root Locus Technique DefinedRoot locus in control system is a graphical approach used to analyze the effects of varying system parameters on the stability and performance of a control system.Advantages of Root Locus Technique Root locus technique in control system is easy to implement as compared to other methods. With the help of root locus we can easily predict the performance of the whole system. Root locus provides the better way to indicate the parameters.This article will frequently use sp

What is State Space Analysis?State Space Analysis DefinitionState space analysis of control systems is a method to analyze both simple and complex systems using a set of variables to describe their behavior over time.State Space EquationsLet us derive state space equations for the system which is linear and time invariant.Let us consider multiple inputs and multiple outputs system which has r inputs and m output.Where, r = u1, u2, u3 ……….. ur.And m = y1, y2 ……….. ym.Now we are taking n state var

Block Diagram DefinitionA block diagram is used to represent a control system in diagram form. In other words, the practical representation of a control system is its block diagram. Each element of the control system is represented with a block and the block is the symbolic representation of the transfer function of that element.It is not always convenient to derive a complex control system’s entire transfer function in a single function. It is easier to derive the transfer function of the contr

Transient Response of Control SystemAs the name suggests transient response of control system means changing so, this occurs mainly after two conditions and these two conditions are written as follows-Condition one : Just after switching ‘on’ the system that means at the time of application of an input signal to the system.Condition second : Just after any abnormal conditions. Abnormal conditions may include sudden change in the load, short circuiting etc.Steady State Response of Control SystemS
