In this paper modeling of an inverted pendulum is done using Euler – Lagrange energy equation for stabilization of the pendulum. The controller gain is evaluated through state feedback and Linear Quadratic optimal regulator controller techniques and also the results for both the controller are compared. The SFB controller is designed by Pole-Placement technique. An advantage of Quadratic Contro...

This paper proposes a decentralized robust constrained cost fuzzy controller (DRCCFC) design for nonlinear descriptor interconnected systems (DIS) with uncertainties. The considered DIS is modeled using Takagi–Sugeno model (T-S FM) rules and strong interconnections. To derive sufficient stability conditions, the quadratic Lyapunov function (QLF) free-weighting (FWF) are defined. In contrast to ...

This paper proposes a systematic procedure for the exponential stabilization of relative equilibria of mechanical systems. The emphasis is on 1 dimensional symmetries. A key design idea is to distinguish between horizontal forces, which preserve the momentum, and vertical forces that affect it. A proportional, derivative control in the horizontal directions and a first order regulator in the ve...

This paper presents an active-set algorithm for large-scale optimization that occupies the middle ground between sequential quadratic programming (SQP) and sequential linear-quadratic programming (SL-QP) methods. It consists of two phases. The algorithm first minimizes a piecewise linear approximation of the Lagrangian, subject to a linearization of the constraints, to determine a working set. ...

This article proposes a power sharing control method based on the linear quadratic regulator with optimal reference tracking (LQR-ORT) for three-phase inverter-based generators using inductor-capacitor-inductor (LCL) filters islanded mode. Compared to single-input single-output (SISO)-based controllers, LQR-ORT controller increases robustness margins and reduces value of error inputs during tra...

Abstract Closed-loop DC Micro-Grid containing sustainable power sources, stockpiling components and burdens are introduced. The regulators for helping the control of mico-grid numerous in power-frameworks, yet most normally utilized one is PI regulator. Aside from there are, an entire bundle independent hybrid that can serve significantly better compared to microgrid framework relevance’s. syst...

A layered stability controller for built. The particle swarm optimization (PSO)-based variable parameter linear quadratic regulator (LQR) upper-level yaw torque lower-level distributor based on pri...

The threat of climate change and diminishing fossil fuels demands nothing short of an energy revolution, a transformation which is already underway as renewable energy markets exhibit enormous and steady growth. This paper presents design of optimal control schemes for Wind Energy Conversion Systems (WECS) based on a time scale technique. The dynamics governing the mechanical components of a va...
