Curious Silly Yours

Source: MathWorks Source: MathWorks   REVISION In previous blog, we saw what is control system , what is  PID controller and it's basic explanation. I really hope you all are familiar with all these concepts and now we can further go to MATLAB/Simulink application of this controller. Steps to Simulation It has always been observed that with low RAM or after internet connection, the MATLAB/Simulink become slow in functioning. The Simulink takes time to open, so using command line to open Simulink would be better. Command Line text for MATLAB Follow the steps after opening the blank Simulink Model now add the following blocks: 1. Transfer fcn 2.  Add block 3. Step 4.  PID block Now connect all this in given formation in this image Now open the transfer function block and configure it like this In this, the array of the numerator coefficients of  s², s and constant, must be written and same as for denominator as highlighted . Now open the PID controller block a...

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 ...
