Application and Performance Assessment of Improved Relay Tuning Method
Abstract: The first order plus time delay (FOPTD) model was considered and the proposed improved relay tuning (PIRT) method was applied to calculate the corrected ultimate gain (Ku) and the optimum PID settings. The closed loop response was obtained using optimum values of PID parameters and compared with that of conventional relay method, Ziegler–Nichols (ZN) method and Cohen–Coon (CC) method. The integral square error as a performance index was used and …

Design of Differential Evolution Optimized PI Controller for a Temperature Process
Abstract: Differential evolution is a new stochastic population-based optimization algorithm. It is an accurate, fast and robust optimization method. In this paper, a PI controller is used and differential evolution optimization technique is used to optimize the controller parameters. The robust controller parameters are obtained by solving the optimization problem, which consists of objective functions and constraints, using differential evolution method. Here differential evolution is implemented in tuning of a PI …

Extended Kalman Filter Application For Launch Vehicle Trajectory
Abstract: Real time applications have been implemented out of intuitive modeling but due to inefficient estimation techniques there were deviations in the results from expected processes. To avoid these deviations for better performance modeling, many mathematical state estimation methods are in use. This paper focuses on a state estimation method for monitoring and control of a real time system. The existing models for state estimation, as well as the challenges associated …

Implementation of Adaptive Control Braking System for Collision-free Driving on Virtual Instrumentation Platform
Abstract: An unaccustomed driver not always has a sound judgment of the surrounding traffic and frequently depresses the brake pedal, causing a poor, jerky drive. Hence, nowadays in high-end cars to provide comfort to passengers while applying sudden brakes without jerks and also in time to avoid collision the adaptive control braking system is used. The main objective of this research study is to automatically monitor the braking force required to …

Model Reference Adaptive Controller for Non-Linear Processes
Abstract: This paper presents the application of adaptive controller for three different non-linear processes and analysing the effect of the controller for three systems which are having different levels of non-linearities. The controller chosen is a direct model reference adaptive controller (DMRAC) for adjusting the feed forward gain using MIT rule. The non-linear systems considered are cylindrical tank, conical tank and spherical tank. The model reference adaptive controller is designed and …

Performance and Analysis of PI Controller using Characteristic Ratio Assignment Method for Coupled Tank Process
Abstract: Control the level of the liquids is a critical need in many industrial processes. Often the tanks are so coupled together that the levels interact and exhibits a nonlinear behaviour. Control of coupled tank system using conventional PI controller, result in poor performance. In this paper the modelling and controller design for coupled tank liquid level process using characteristic ratio assignment (CRA) method is implemented. CRA method is an approach …
