Abstract
A novel technique for load frequency control of a multi-area power system with state observer is proposed in this paper. State observer based model overcomes the difficulty in continuous system state measurements which forms the main drawback in the application of linear quadratic regulator. This paper presents a combined estimation of state and optimal gain so that uncertainties in the system and variation in system parameters can be successfully accommodated. Augmenting the optimal controller gains to state variables results in non-linearity in the system model and hence Extended Kalman filter is used for the combined estimation. A comparative analysis based on Monte Carlo simulations of a two area power system under different measurement noise variances are included for the validation of proposed control technique. Matlab Software for Disciplined Convex Programming toolbox is used to verify the convergence of proposed technique. To ensure the effectiveness of the proposed technique, it is applied to a control area linked with an interconnected system including real time simulations using PSCAD.
This paper presents a disturbance observer–based model predictive control strategy for the position regulation of a twin rotor MIMO system (TRMS). The nonlinear dynamics of the TRMS are first rewritten as an uncertain linear time invariant (LTI) system with additive disturbances. An extended state observer (ESO) is the...

In the multi-motor drive systems, the backlash nonlinearity and the external disturbances should be taken into their modeling, which is essential to design the safer and more efficient load tracking and motor synchronization control strategies. An extended state observer-based optimal control method for the multi-motor...

This paper investigates the output regulation problem using an observer-based inverse optimal controller within the nonlinear servomechanism framework for asymptotic convergence to desired references and rejection of time-varying disturbances generated by an exosystem. To address the practical constraint of full-state...
This paper proposes a robust state feedback control strategy for variable speed wind energy conversion systems (WECS) within the Takagi-Sugeno fuzzy (TSF) modeling framework. A T-S fuzzy representation is used to approximate the nonlinear aerodynamic behavior of the wind turbine. This representation enables to design a...
