Field Oriented Control

AC Induction motors offer enviable operational characteristics such as robustness, reliability and ease of control. They are extensively used in various applications ranging from industrial motion control systems to home appliances. However, the use of induction motors at its highest efficiency is a challenging task because of their complex mathematical model and non-linear characteristic during … Read more

Control Engineering | Historical Review and Types of Control Engineering

Control system engineering is the branch of engineering which deals with the principles of control theory to design a system which gives desired behavior in a controlled manner. Hence, this is interdisciplinary. Control system engineers analyze, design, and optimize complex systems which consist of highly integrated coordination of mechanical, electrical, chemical, metallurgical, electronic or pneumatic … Read more

On Off Control Theory | Controller

Sometimes, the control element has only two positions either it is fully closed or fully open. This control element does not operate at any intermediate position, i.e. partly open or partly closed position. The control system made for controlling such elements is known as on off control theory. In this control system, when process variable … Read more

Control System | Closed Loop Open Loop Control System

When a number of elements are combined together to form a system to produce desired output then the system is referred to as control system. As this system controls the output, it is so referred. Each element connected to the system has its own effect on the output. Definition of Control System A control system … Read more

Types of Control Systems | Linear and Non Linear Control System

Before I introduce you the theory of control system it is very essential to know the various types of control systems. Now there are various types of systems, we are going to discuss only those types of systems that will help us to understand the theory of control system and detail description of these types … Read more

Types of Controllers | Proportional Integral and Derivative Controllers

Before I introduce you about 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 steady state accuracy by decreasing the steady state errors. As the steady state accuracy improves, the stability also improves. … Read more

Now before we discuss this topic in detail it is very essential to know, what is the need of a digital technology though we have … Read more

Block Diagrams of Control System

The block diagram is to represent a control system in diagram form. In other words practical representation of a control system is its block diagram. It is not always convenient to derive the entire transfer function of a complex control system in a single function. It is easier and better to derive transfer function of … Read more
