Frequently asked questions
Q1: How traffic lights are examples of Control system?
A1: Traffic lights is a best example of control system. In traffic signals, a sequence of input signal is applied to the control system and the output is one of the three lights that will be on for some duration of time. While one of the lights is on, the other two lights will be off. Based on one of the traffic studies at a particular junction, the on and off times of the lights can be determined. Hence traffic signal lights control system operates on time basis as the input controls the output.
Q2: What is SISO and MIMO Control systems?
A2: Based on the number of inputs and outputs present, Control Systems can be classified as SISO control systems and MIMO control systems. Single Input and Single Output (SISO) control systems have one input and one output. Whereas, Multiple Inputs and Multiple Outputs (IMO) control systems have more than one input and more than one output.
