Simplified Model Characterization and Control of an Unmanned Surface Vehicle

Journal of Marine Science and Engineering
This study presents the modeling and control of the unmanned surface vehicle (USV) SABALO. Two models were built, one based on a transfer function matrix and another based on state variables, and from these models, two control strategies were developed ...

Advanced backstepping control based on ADR for non-affine non-strict feedback nonlinear systems

Automatika, 2018
Few results are made on non-affine non-strict feedback nonlinear systems, which is a challenging problem in the control theory. In this paper, a novel control method based on an advanced backstepping and auto disturbance rejection is presented for a ...

Dynamics analysis of permanent magnet synchronous motor speed control with enhanced state feedback controller using a linear quadratic regulator

Heliyon
This paper presents a robust speed regulation and control of a permanent magnet synchronous motor (PMSM). A linear quadratic regulator (LQR) based state feedback controller was developed to achieve a successful suppression of periodic disturbance of ...

Linear Algebra-Based Multivariable Controller Design for Gas Turbine Machines with State-Derivative Feedback

Machines
This paper presents a linear algebra-based control algorithm for multivariable gas turbine systems using matrix polynomial theory and the Kronecker product to assign block roots (i.e., block eigenvectors with prescribed latent structure). State and state-

Robustness of the quadratic partial eigenvalue assignment using spectrum sensitivities for state and derivative feedback designs

Journal of Low Frequency Noise, Vibration and Active Control, 2018
Based on the notions of spectrum sensitivities, proposed by us earlier, we develop a novel optimization approach to deal with robustness in the closed-loop eigenvalues for partial quadratic eigenvalue assignment problem arising in active vibration ...

Robust State Feedback Control With D-Admissible Assurance for Descriptor Systems Subjected to Perturbed Derivative Matrix

IEEE Access
This work mainly addresses the state feedback control with D-admissible assurance for descriptor systems subjected to perturbed derivative and systems’ matrices simultaneously. By the linear matrix inequality (LMI) and matrix algebra manipulation,

Boundary Feedback Control of a Cascade System of Fractional PDE-ODEs

Fractal and Fractional
The fractional PDE-ODE coupled system with Neumann boundary condition is considered in this paper. We design a boundary state feedback controller using the Backstepping method to stabilize the considered system. According to operator semigroup theory, we

Dynamics of a state-dependent delay-differential equation

Electronic Journal of Qualitative Theory of Differential Equations
We present a detailed study of a scalar differential equation with threshold state-dependent delayed feedback. This equation arises as a simplification of a gene regulatory model.
