The Inverted Pendulum; Analysis, Design & Implementation is a collection of MATLAB functions & scripts, and SIMULINK models, useful for analyzing Inverted Pendulum System and designing Control System for it.
The Inverted Pendulum is one of the most important classical problems of Control Engineering. Broom Balancing (Inverted Pendulum on a cart) is a well known example of nonlinear, unstable control problem. This problem becomes further complicated when a flexible broom, in place of a rigid broom, is employed. Degree of complexity and difficulty in its control increases with its flexibility. This problem has been a research interest of control engineers. In this submission, however, we have analyzed Inverted Pendulum only with rigid broom.
The aim of this study is to stabilize the Inverted Pendulum such that the position of the carriage on the track is controlled quickly and accurately so that the pendulum is always erected in its inverted position during such movements.
The inverted pendulum (IP) is among the most difficult systems to control in the field of control engineering. Due to its importance in the field of control engineering, it has been a task of choice to be assigned to Control Engineering students to analyze its model and propose a linear compensator according to the PID control law.
The work included in this submission has been carried out in the
Instrumentation and Control Lab at the Institute of Industrial Electronics Engineering, Karachi, Pakistan.
The author would like to thank Dr. Ken Dutton [School of Engineering, Sheffield Hallam University, UK; Author: "Art of Control Engineering"] for his review of this submission.
i tried to design a swing up controller based on energy control.I just calculated the energy of pendulum and find maximum acceleration about the pivot and calculated the corresponding voltage signal and then feedback it to the system. But it won't produce correct results . I obtained graphs which is correct up to 0.325seconds after that the controlling is lost. Can you pls guide me?
Hi! I took a look on your paper work and I find it very interesting and complete. I had to develop a project about an Inverted Pendulum and this was very helpful.
However, when I put a scope on the PID law (ipcstep.mdl), I saw an infinite command (~2.2*exp15). I think this is the result of simplifying an unstable zero by introducing an integrator.
I would like to know your response; maybe I’m wrong, but I need your help for my project.
A million thanks,
Hi, may I know if it is possible to keep the pendulum balanced at a desire angle from the vertical without the cart below going to infinity? Thank you.
Very Nice I've also used here http://www.mathworks.com/matlabcentral/fileexchange/25139
It's the Inverted Pendulum control simulation with SimMechanics in Simulink
Great Job - very detailed! I just want to mention something that seems a bit confusing. You state that the steady state error is zero in response to a unit step input, but the output is 0.35 rather than 1. The open loop transfer function is a type zero, which would not be able to render a zero steady state error in response to a step input. I was able to calculate a steady state error of 0.65, which leads to the output of 0.35. I'm certainly not an expert, and might be analyzing this incorrectly, but wanted to make note of it since the paper seems so complete otherwise.
Comprehensive, helpful, thorough. Excellent example.
Very good work.Keep it up
very important work
The over all assessment of the problem is good. The control of inverted pendulum using fuzzy systems is needed
I am a student in electronic
It was very useful for me as a good tutorial for Matlab Control and also my very elementary control learning course(Linear Control)
It will be very usefull for the research peoples who want to validate their results in real time systems.
I have some delusions and dissociations about Inverted Pendulum.
I developed new type Inverted Pendulum for gain-scheduling control theory in Japan.
If you have any intersts for this message please contuct me.
i want some file
its very help full for beginners now i am doing the same by using model predictive control technique.if any body have suggestions please give me at firstname.lastname@example.org
Most complete paper on this subject!
Very good work!
I can't open...error in acrobat.
Hi Khalil Sultan, all good one. I found its site in the Internet and I liked it very content about controlling using matlab. By chance you have some you would materia on the controlled inverted pendulum for logic fuzzy.
I am thankful since already for the attention, Gledson Melotti.
I want to ask u something. Supposing we have the pendulum at 0 degrees angle and we want to force it to go to 180 degrees angle. Can u help me write this code?
i think u are not concidering the moment of inertia of the connector. it may be a significant factor if we are using a solid connector
am doing a project in inverted pendulum so hope this might help me in anyways
NICE WORK CARRIED OUT BY MINE UNIVERSITY ONE YEAR SENIOR GRADUATES ..
REALLY IT HELPED US IN INSTITUTE OF INDUSTRIAL ELECTRONICS ENGINEERING IIEE ,KARACHI PAKISTAN IN OUR CONTROL SYSTEMS LAB.. ESEPCIALLY IN DESIGN PARAMETRES SELECTION
Dung cai toi dang tim
THANK YOU VERY MUCH
thank you.your paper have help me a lot.thank you very much.
Your paper is very good.
Good god that is fantastic!
As a Master's student in the US, hats off to the author! This is truly an excellent presentation.
I'd love to see it redone, though, using State-Space, and LQR techniques rather than Classical Design Theory!
A wonderful work! Thank you!
thank you, I'm started studying controls recently and that was very helpful on my education.
