Control System What is Control System? The control system is responsible for the behavioural response of any system with input and output ports. It deals with the response of any system with input conditions and corresponding output.  There are 2 types of systems: Continuous System (represented in s-plane and in Laplace form) Discrete System (represented in z-plane and in Z-transform) The input I(s) means continuous input signal and O(s) means continuous output signals to the system represented as H(s). The transfer function means the ratio of output to input in any domain. The transfer function equation  H(s) = O(s)/ I(s) This equation is for continuous form of system when the initial condition is 0. There are 2 types of loop system, i.e., a) open loop, b) closed loop system. The above H(s) system is an open loop system as it does not have any output connected to input. In the closed loop system, the input of the system is added with the output of the system. This is also ...

PID Controller What is PID? PID stands for Proportional Integral Derivative controller. It is one of the modern controller technique that use negative feedback in order to have proper required output. To make it understand let me use some analogy of riding a bike. Let say we are riding a bike on a highway with some no rmal traffic. To accelerate, we will rotate the knob on the right handle, so the vehicle will accelerate in proportional to how much the knob is rotated at that time. This is known as Proportional controller . We increase and decrease the acceleration according to our need and proportionally with the help of knob. In this, we are maintaining our speed to move constantly on the path. Now, there is a hill the bike need to climb. In order to maintain the same speed, we quickly apply more acceleration to gain same speed on the hill so that the vehicle do not slow down. This is called as Derivative control. Whenever there is a large error in speed achievement, it can be ac...
