This paper discusses the control of an ideal reactive distillation column (RDC) using model predictive control (MPC) based on a combination of deterministic generalized orthonormal basis filter (GOBF) and stochastic autoregressive moving average (ARMA) models. Reactive distillation (RD) integrates reaction and distillation in a single process resulting in(More)
The Quadruple Tank Process (QTP) is a well-known benchmark of a nonlinear coupled complex MIMO process having both minimum and nonminimum phase characteristics. This paper presents a novel self tuning type Dual Mode Adaptive Fractional Order PI controller along with an Adaptive Feedforward controller for the QTP. The controllers are designed based on a(More)
In this paper, the concept of principal component analysis (PCA) has been used to generate a residual space to detect an actuator and a sensor fault in a two non-interacting tank system. Since there is only one residual vector in the present case, isolation of faults using PCA is not feasible. For isolation of the fault, partial PCA based structured(More)
This paper presents an interesting phenomenon unobserved so far in literature to the best of the authors' knowledge in fractional-order chaotic systems (FOCSs). It is the rotational phenomenon of fractional-order coexisting attractors. Another significant feature of the newly proposed FOCS is that two 2-wing chaotic attractors coexist in its(More)
Inverted pendulum is widely used in the study of control theory. There are different types of inverted pendulums available, out of which a rotary inverted pendulum (RIP) with an L-shaped arm is considered in this work. The aim of this work is to stabilize the pendulum at its vertical upright position with minimum oscillations in both the pendulum and(More)
— This paper deals with design and implementation of controllers to stabilize a ferromagnetic ball in a Magnetic Levitation (Maglev) system and control the ball position to track a reference signal within an operating region. For this purpose, PID and Fractional Order PID (FOPID) controllers have been designed using Particle Swarm Optimization (PSO),(More)
