34. Frequency-Domain Tuning of a Robust Optimal 2-DOF Fractional Order PID Controller for a Maglev System

Author

Dey, Soham, Banerjee, Subrata, and Dey, Jayati

Abstract

Two-degree-of-freedom (2-dof) proportional-integral-derivative (PID) controllers are better than the 1-dof counterpart in the sense that the former can predominantly reduce large overshoot and settling time without affecting the steady-state performance provided that a suitable tradeoff is chosen between reference tracking and rejection of the disturbance signal. Again, fractional order (FO) calculus is suitable to realize the dynamics of a controlled system and smoothen control action. This article amalgamates both of these control actions and develops a novel 2-dof FOPID controller for stabilization and precise position control of an unstable and nonlinear magnetic levitation system. A set of frequency-domain parameters are optimized to evaluate controller's orders and gains by adopting equilibrium optimizer, a new and efficient technique in the field of modern metaheuristics algorithms. It has been observed that the proposed 2-dof control architecture outperforms the 1-dof control counterpart in terms of time- and frequency-domain indices, reference tracking, robust stability analysis, and cancellation of disturbance signal. The efficacy of the proposed controller has been verified by comparing performance characteristics with existing controllers both in simulation and experimentation.

Abstract

Background/Aim: The recent pandemic of Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2) is yet another scourge from the coronaviridae family that causes illnesses ranging from common cold to more severe diseases such as Middle East respiratory syndrome (MERS-CoV) and severe acute respiratory syndrome (SARS-CoV). The numbers are still on the rise, despite a country wide lockdown and yet no definitive drugs and or/vaccines are available to manage the active COVID-19 cases. Methods: The present research design was a hospital based observational descriptive study conducted at S. M. S. Medical College and Attached hospitals, Jaipur, that analysed data of all the patients with COVID-19 related mortality, admitted between 1 April to 4 May 2020. Patients included in this study were RT-PCR confirmed cases of SARS-CoV-2 using nasopharyngeal and oropharyngeal swab samples. Results: The mean age of patients with COVID-19 related mortality was 53.41 ± 18.42 year with majority of patients belonging to age group of more than 60 years (41.18 %) followed closely by COVID-19 positive patients in age range of 45 to 60 years (33.33 %). The male to female ratio was 1.68: 1. Mean time lag between hospitalization and death reported was 6.18 days. Majority of the patients admitted (72.5 %) succumbed within 3 days of hospitalization. Eleven patients (21 %) were brought dead to the hospital who were tested COVID-19 positive after death. Most common comorbidity reported in patients with COVID-19 related mortality was hypertension (30 %) followed by diabetes mellitus (27.5 %). Conclusion: Hypertension and diabetes mellitus might be independent risk factors making an individual susceptible to COVID-19 related death. Elderly patients also have a greater risk of mortality. The non-availability of definitive management protocol and/or vaccine against COVID-19 makes public health preventive measures of social distancing, use of masks and frequent handwashing an important modality in the fight against COVID-19.

46. Control of Generalized Decoupled MIMO Systems Based on Linear Programming Method.

Abstract

In this work, a control method is suggested to generalize decoupled multi-input multi-output (MIMO) plant to get satisfactory results. The phenomena of decoupling converts a $ p \times q $ p × q MIMO plant to $ p $ p number of equivalent single-input single-output (SISO) loops which enables one to control $ q $ q number of outputs independently even due to the effect of coupling present in control inputs and outputs. The effect of these cross-couplings causes the disturbances. The decoupler aim is to eradicate the effect of these disturbances on outputs. In order to achieve it, this work proposed a novel generalized decoupling technique on the basis of linear programming. Infinity $ (\infty) - $ (∞) − norm method is considered to minimize the effect of decoupler gain of the cross-couplings of the MIMO system, over all frequencies, that minimizes undesired mutual couplings of the resulting decoupled plant also nullifying coupling effect completely at steady state as well. The proposed method of decoupling is compared with the relative gain array (RGA) and further modified RGA (MRGA) technique of decoupling which is also elaborated in this paper. To achieve the desired response from the decoupled plant proportional integral derivative (PID) control method is suggested using the Kharitonov theorem. The ensued technique is employed on different types of MIMO systems including square, non-square and time-delayed. [ABSTRACT FROM AUTHOR]
