This paper offers an H-infinity (H∞) controller-based disturbance rejection along with the utilization of water wave optimization (WWO) algorithm. H∞ controller is used to synthesize guaranteed performance certain applications as well it provides maximum gain at any situation. The proposed work focuses on conflicts continuous stirred-tank reactor (CSTR) such variation in temperature and product...

In this paper we propose a control system design methodology which has two main objectives: the first one is to achieve control system specifications for a local H∞ controller designed for a given operation condition, and the second objective is to provide a procedure for bumpless transfer (BLT) when the controller is switched to another one, due to change in the operation condition, or when th...

An approach of reduced-order H∞ controller for a class of linear continuous dynamic systems is presented based on Genetic Algorithm. Necessary and sufficient conditions are given, in terms of linear matrix inequality, for the existence of controller. A rank condition is changed to object function of genetic algorithm(GA). The minimum order nk of the controller and a corresponding parameter pair...

in this paper, a recurrent fuzzy-neural network (rfnn) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...

Abst raet Visual servo system is (I robot control system which incorporates the vision sensor i n the feedback loop. Since the robot controller is also i n the visual servo loop, compensation of the robot dynamics is important f o r high speed tasks. Moreover estimation of the object motion is necessary for real time tracking because the visual information includes considerable delay. T h i s p...

In this paper the synthesis of logic-based switching H2/H∞ state-feedback controller for singular perturbation systems is considered that achieves a minimum bound on the H2 performance level, while satisfying the prescribed H∞ performance. The proposed hybrid control scheme is based on a fuzzy supervisor which manages the combination of two controllers. A convex LMIbased formulation of the two ...

TCP becomes inefficient and prone to instability when its bandwidth-delay product increases. By sending explicit congestion information from routers to end hosts, both XCP and API-RCP have been proposed to solve the stability issue of TCP in high bandwidth-delay product networks. Since the estimation errors of the network parameters are unavoidable, we would like to design a robust controller t...

This paper proposes a novel method to designing an H ∞ PID controller with robust stability and disturbance attenuation. This method uses particle swarm optimization algorithm to minimize a cost function subject to H ∞ -norm to design robust performance PID controller. We propose two cost functions to design of a multiple-input, multiple-output (MIMO) and single-input, single-output (SISO) robu...

In this paper, a structure-specified mixed H2/H∞ controller design using particle swarm optimization (PSO) is proposed for control balancing of Bicyrobo, which is an unstable system associated with many sources of uncertainties due to un-model dynamics, parameter variations, and external disturbances. The structure-specified mixed H2/H∞ control is a robust and optimal control technique. However...
