Dr Vipin JainWhat is Steady State Error? Steady-state error is defined as the difference between the desired value and the actual value of a system output in the limit as time goes to infinity (i.e. when the response of the control system has reached steady-state). Steady-state error is a property of the input/output response for a linear … Read more
What is Open Delta Connection An open delta connection transformer uses two single-phase transformers to provide a three-phase supply to the load. An open delta connection system is also called a V-V system. Open delta connection systems are usually only used in emergency conditions, as their efficiency is low when compared to delta-delta (closed delta) … Read more
What is Nyquist Criteria Nyquist stability criterion (or Nyquist criteria) is a graphical technique used in control engineering for determining the stability of a dynamical system. As Nyquist stability criteria only considers the Nyquist plot of open-loop control systems, it can be applied without explicitly computing the poles and zeros of either the closed-loop or … Read more
Before I introduce you to various controllers in detail, it is very essential to know the uses of controllers in the theory of control systems. The important uses of the controllers are written below: Controllers improve the steady state accuracy by decreasing the steady state error. As the steady state accuracy improves, the stability also … Read more
