Most of the time we use Simulink to simulate a PID controller. But this files run it as a Matlab code.
Extract the files to the working directory and just run the file PID_ctrl_call.m.
You can vary the PID tuning parameters in the file pid_ctrl.m and see what will happen.
Digital version of Fractional-Order PID Controller (DFOC) of the form:
C(s) = K + Ti/s^m + Td*s^d for given sampling period Ts [sec].
For more details and help write:

This code uses gui to demonstrate the step response for DC Motor Position system with PID controller which can be edited by three sliders. The edit texts can be edited by user, after editing press plot pushbutton to plot the response of new...
The recipe gives simple implementation of a Discrete Proportional-Integral-Derivative (PID) controller. PID controller gives output value for error between desired reference input and measurement feedback to minimize error value.
This simulation illustrates the effects of the fixed-point
computations on the closed-loop precision for a 16-bits PID controller.
The rounding mode, the point where the truncations take place and the
format width for the internal...
A very simple and effective way to build a PID controller in a single m.code
This code generates a PID controller in MATLAB environment without using any built-in commands or simulink blocks.
Tune this PID by changing the Kp, Ki, Kd,...
PID Controller Optimizer is a MATLAB based interface written by the author and it can be used to optimize PID parameters for the plant model defined by the user. In the package, Simulink is used in modelling the plant, which can be SISO...
This technique is used in many control application and here i used it to tune the PID controller
PID controller has been extensively used in the industrial world. But in this controller it is difficult to tune the PID gains.
We apply the genetic algorithm(GA) to tune the PID gains. The GA is agorithm using the biotic; gene the...
This is the demo file for MathWorks webinar "PID Control Made Easy" from September 201-
The demo shows design and tuning of PID controllers in MATLAB and Simulink.
PID Controller is used to control engine speed.
This is the demo file for video demo:
and "Seth on Simulink" blog post "PID Control Made Easy":
The effect of fixed-point arithmetic in 16-bits PID controller C routines
on the closed-loop precision is shown in this Simulink model.
Two Simulink blocks that implement single and double
precision 16-bits PID C routines are...
The PID controller is the most widely used controller in industrial systems. However, appropriately tuning a PID controller is not an easy task although it has only three parameters at most.
This submission provides a tool for beginners...
This is the demo file for September 2009 MathWorks webinar "PID Control Made Easy":
and November 2009 MATLAB Digest article "PID Control Design Made...
PID is used in several purpose for controlling of motors and valves etc..., no development was in the field of state space model w r t PID controller design .... hope this suits the requirement
Method 1 . Using Step Response and Delay Time and Time Constant Parameters.
Method 2 . Using proportional controller action only. you should find critical gain and corresponding critical period.
all results come in 2...
Particle swarm optimization is a technique used in many control systems application. Here i used the PSO in PID controller tuning
It is inverted pendulum. Down point is base can be controlled. It can be moved horizontally only. PI (not PID) controller used to set the pendulum in up direction. There are friction in base and frictiopn from air...
THIS PROGRAMME ILLUSTRATES THREE INTRODUCTION PART OF CONTROL SYSTEM :-
1- MODEL REDUCTION OF A HIGHER ORDER SYSTEM TO FIRST/SECOND ORDER SYSTEM
2- CONTINEOUS TIME PID CONTROLLER DESIGN ACORDING TO FIRST/SECOND ORDER SYSTEM CONTINEOUS...
DC motor Control using lag compensation and PID
To customize this code you just need to:
1- Change the values of DC motor constants
2- Determine settling time, PO% and SSE and Change the zeros of lag compensation
3- Tune the...
