This paper proposed a new approach of controller design. By using model matching method we design a PID controller for higher order system. A higher order model is reduced by Pade approximation and mixed method, then design a controller for reduced order model. We take a comparatively study between close loop response of higher order system and reduced order system. The model order reduction an...

In this paper an adaptive PID controller for Wind Energy Conversion Systems (WECS) has been developed. Theadaptation technique applied to this controller is based on Reinforcement Learning (RL) theory. Nonlinearcharacteristics of wind variations as plant input, wind turbine structure and generator operational behaviordemand for high quality adaptive controller to ensure both robust stability an...

The purpose of introducing a combined cycle with gas turbine in power plants is to reduce losses of energy, by effectively using exhaust gases from the gas turbine to produce additional electricity or process. The efficiency of a combined power plant with the gas turbine increases, exceeding 50%, while the efficiency of traditional steam turbine plants is approximately 35% to 40%. Up to the pre...

This paper investigates the operation of a hybrid power system through a novel fuzzy control scheme. The hybrid power system employs various autonomous generation systems like wind turbine, solar photovoltaic, diesel engine, fuel-cell, aqua electrolyzer etc. Other energy storage devices like the battery, flywheel and ultra-capacitor are also present in the network. A novel fractional order (FO)...

Renewable energy-based hybrid power systems are being increasingly deployed across the globe to reduce carbon emissions. The system frequency and tie-line tend fluctuate due operating conditions. These fluctuations can be maintained within desired limits using optimally designed controllers. In this article, recently developed improved squirrel search algorithm (ISSA) is used tune parameters of...

This paper deals with the fractional order multi-loop controller design for a distillation column. The idea is generalization of IMC-PID-FOF method developed monovariable systems to column model which multivariable. principle based on IMC paradigm and choice appropriate control configuration minimum interactions. proposed illustrated an example taken from literature.

The self-tuning PID/I controller (ST-PID-2) with new algorithm of tuning of test signal is proposed. This controller is based on the self-tuning PID/I controller (ST-PID-1) but have better algorithm of tuning of test signal. It is assumed that plant is described by first order with time delay. Coefficients of plant are unknown and can be changed in some isolated time moments. Self-tuning PID/I ...

The introduction of electrolytic aluminum load in a large-scale power system with complex station structure is essential for frequency control (LFC). In this paper, we propose strategy to participate the modulation grid based on IEEE standard two-region LFC model. Besides, fractional-order PID (FOPID) controller designed and compared traditional PID, parameters FOPID are optimized by PSO algori...

Fractional-Order Controllers (FOC) extend PID controllers by using non-integer order integral and derivative actions. They have many advantages even if the tuning methods are still at their infancy. Hence we apply Differential Evolution (DE) optimization to tune parameters of FOC in a unitary feedback linear control system of a first order plana with a lag plus an integrator. The FOC combines t...
