Article
An analytical expression for the exact identification of two-input two-output (TITO) process using hysteresis relay is presented in this study. The identified transfer matrix consists of four independent first-order plus delay time (FOPDT) models and the time constants, delays and the gains of the FOPDT models are obtained from the limit cycle meas...
Article
This paper presents design of multivariable PID controller using a novel method differential evolution (DE)-based particle swarm optimisation (PSO) for two-input two-output (TITO) processes and its performance compare with evolutionary algorithms (EAs) like DE and modified PSO methods. In the proposed DE-PSO method, preliminary DE is applied on the...
Conference Paper
In this paper, PI-PD controller is designed for stable and unstable Single-Input Single-Output (SISO) processes. At first, the expression is derived using Routh stability criteria for Proportional-Derivative (PD) controller to stabilize the process then Proportional-Integral (PI) controller parameters are designed using Modified Particle Swarm Opti...

Trajectory tracking and stabilization of a nonlinear single stage inverted pendulum is a complicated control problem, as nonlinearity is present inherently and external factors affect the equilibrium position. Sliding mode control (SMC) is a robust control technique, most popular for nonlinear system's controlling. In this paper, a new model based...
Article
In this paper, a method for the identification and control of stable and unstable processes is proposed. Firstly, a second-order plus delay time process model is identified using an ideal relay in the feedforward path and then, a proportional integral-proportional derivative (PI-PD) controller is designed based on the identified process model. The...
Conference Paper
A PID-P controller is designed for a class of nonLinear processes using Cuckoo Optimization (CO) techniqe, where a proportional controller is used in the inner feedback loop which increases the stability of the non-linear process and the PID controller is connected in feed forward path for desired response. The objective function for CO optimizatio...
Conference Paper
In this paper, a new tuning algorithm for PID controller based on gain margin and phase margin concept is proposed. The controller parameters are dependent on single parameter, which are subjected to a desired phase margin, and a minimum required gain margin constraint. The main advantage of the proposed tuning algorithm with respect to previous wo...
Conference Paper
In this paper, performance comparison of evolutionary algorithms (EAs) such as modified particle swarm optimization (MPSO) and improved asynchronous particle swarm optimization (IAPSO) is considered. EAs simulations are carried with minimization of IAE and peak overshoot as objective using one type of stopping criteria, namely, maximum number of it...
Conference Paper
In this paper, a Modified Particle Swarm Optimization (MPSO) algorithm for optimizing the Proportional-Integral-Derivative (PID) controller parameters for stable process is presented. The proposed algorithm is to modify the velocity and position formula of the conventional PSO technique in order to improve computational efficiency and time complexi...
Article
A simple model-based PI-PD control method is proposed for stable and unstable processes. Initially, the proportional-derivative PD controller is used to stabilise the process and then, proportional-integral PI controller parameters are estimated using the particle swarm optimisation PSO algorithm. The PSO is the stochastic evolutionary techniques t...
Conference Paper
Loop interaction is an important issue in the identification problem of multi input multi output (MIMO) processes. This paper presents a new approach to identify two input two output (TITO) processes using Relay based identification technique where interaction between the loops can be reduced to a acceptable limit. In the proposed structure two rel...
Conference Paper
In this paper presents a noval approach to design of PID controller for two input two output (TITO) system using Particle Swarm Optimization (PSO) technique. The PSO technique is used to find the global optimum values of PID parameters for TITO processes which help in easy implementation, stable convergence characteristic, better computational effi...
