State Space Analysis

State space analysis is an important method or procedure used in control systems where we can analyze and design of dynamic systems. Its responsibility is to provide detailed and comprehensive analysis for the particular module required. The representation is done by state equation. Therefore, it provides a systematic framework so that we can meet desired performance specifications.

What is a Control System?

A Control system is a set of electronic devices that regulates or directs the behavior of other devices or systems according to the principle of the input-process-output cycle to achieve the desired output. The widely used areas of control systems are electronics, automation, and engineering....

Introduction to Control Systems

A control system is a system which works according to the principle of I-P-O cycle, that is, it takes input and processes the desired output accordingly as human brain works or can say a computer system works. Here, you can analyze, the desired output is completely controlled by the given input, therefore, it is named as control system....

Classification

As control system works on the principle of I-P-O cycle and controlling the output by the respective input, it contains multiple parameter. Due to this, it is classified into multiple types depending upon some parameters or factors. Parameters or factors can be on the basis of types of signals, nature and number inputs and outputs, feedback mechanisms, linearity, time based, etc....

Feedback

Feedback is nothing but the acknowledgement of the output given to the respective input. If output requires some modification or changes or any anything else from the input side, it get back to it and act as an input. In simple words, When output comeback to the respective input, and act as a new input, called as feedback of the control system....

Mathematical Models

Mathematical models are the representation of set of action in terms of mathematical expression and equations. We can understand the input – output procedures by using mathematical models by which we can analyze the structure and design of the control systems. It can be done by using models such as differential equation model, transfer function model and state space model....

Block Diagram in Control System

Block diagram is the representation of data in the form of block or set of blocks, will give a pictorial representation. It is beneficial as it represents the data in a very easy and clear way to analyze the control system. It gives a clear picture of the control system so that we can easily analyze the design....

Time Response and Time Domain Analysis

Time Response and Time Domain Analysis are important components of control systems where we can analyze the response or behavior of the systems with different inputs according to the time. First, we will see time response analysis where we will understand transient response and steady state response, then we will go through standard test signals and its classification. Secondly, we will see time domain analysis along with the performance measures like rise time, setting time, overshoot and steady state error....

Stability Analysis

Stability is an important concept in control system regarding the state of the output. If the output of the control system is under control then the system is considered as stable otherwise unstable. We can say that, the stability of the system is completed dependent on the system output....
