Optimization of Pid Parameters Based on Particle Swarm Optimization for Ball and Beam System

Abstract

This paper introduces the application of an optimization technique, known as Particle Swarm Optimization (PSO) algorithm to the problem of tuning the Proportional-Integral-Derivative (PID) controller for a linearized ball and beam control system. After describing the basic principles of the Particle Swarm Optimization, the proposed method concentrates on finding the optimal solution of PID controller in the cascade control loop of the Ball and Beam Control System. Ball and Beam control system tends to balance a ball on a particular position on the beam as defined by the user. The efficiency of Particle Swarm Optimization algorithm for tuning the controller will be compared with a classical method, Trial and Error method. The comparison is based on the time response performance. The two tuning methods have been developed by simulation study using Matlab\ m-file software. The evaluations show that Evolutionary method Particle Swarm Optimization (PSO) algorithm gives a much better response than trial and error method.

Integrated Intelligent CAD System for Interactive Design, Analysis and Prototyping of Compression and Torsion Springs

“…Deployment of AI (artificial intelligence) technologies into the existing CAD systems is a very efficient way of implementing an intelligent design workspace that is mainly featured on creativity. The developed Springs IICAD system represents one of the AI techniques called KBS (knowledge-based system), meaning ES (expert system), based on knowledge [27][28][29]. A designer, in an interaction with a computer, can simultaneously conduct multiple activities during the design process of the spring.…”

An Optimal Quantitative PID Controller Design for Ball and Beam System

“…Mehedi et al [7] in 2018 proposed Fractional Order PD Control (FOC) to control the ball position. Ali et al [8] in 2018 proposed PID controller to stabilize the system, PSO method was used to tune parameters of the controller. Shah et al [9] in 2018 proposed LQR controller to control the system.…”
