Time-Variant and Invariant Control System

Control systems play an important role in engineering, they help in regulating and controlling a process or a system to obtain controlled output. There are different types of control systems such as Linear and non-linear systems, Causal and Non-causal systems. Time variant and Time invariant control systems are one of them. In this article, we’ll learn about the time-variant and invariant systems.

Time-Variant System

A system is said to be a time-variant system if its input /output characteristics change with time. If the control system is time-dependent then it is known as a time-variant control system.In a time variant system time shift in the output signal differs from the time shift in the input signal.Examples: Medical Ventilators, Agricultural Robots, Air Conditioner...

Time-Invariant System

A system is said to be time-variant if it’s input/output characteristics does not change with time. if a control system is time independent then it is known as time-variant control system.In time-invariant control system time shift in output signal is same as the time shift in the input signal.Examples:- Thermostats, Traffic lights, Elevator Control, Water Tank Level Control...
