This paper develops a PI-like interval type-2 (IT2) fuzzy maximum power point tracking (MPPT) control method for a class of wind power generation and battery charging systems with DC/DC buck converters. After the brief model descriptions of the wind power turbine, generator and DC/DC buck converter, the proposed MPPT controller is designed using IT2 fuzzy control logics and its asymptotical sta...

This article addresses the design of PID, I-PD and PD-PI controller for the ball and beam system. The ball and beam system, a non linear one, has been linearised around the equilibrium point to obtain the linearised model transfer function. The PID controller has been tuned using ITAE criterion and the same set of parameters has been utilized for designing both the I-PD and PD-PI controller. Th...

Control of Induction Motor (IM) is well known to be difficult owing to the fact the mathematical models of IM are highly nonlinear and time variant. The advent of vector control techniques has solved induction motor control problems. The most commonly used controller for the speed control of induction motor is traditional Proportional plus Integral (PI) controller. However, the conventional PI ...

This paper presents an intelligent speed control system based on fuzzy logic for a voltage source PWM inverter-fed indirect vector controlled induction motor drive. Traditional indirect vector control system of induction motor introduces conventional PI regulator in outer speed loop; it is proved that the low precision of the speed regulator debases the performance of the whole system. To overc...

Traditionally in servo systems, the PI(D) controller has been widely used, while other types such as the PDF controller has been applied in some applications. In this article, the PDFF controller which has feedforward term in addition to a conventional PDF(Pseudo-Derivative Feedback) controller is introduced. Tracking and regulation characteristics of the PDFF controller in motion control appli...

In an industrial boiler system, multiloop (decentralized) proportional-integral (PI) control is used because of its implementational advantages. We show that such control schemes sacrifice robustness and performance of the overall system. In particular, under normal boiler operating conditions, we design a robust multivariable controller using loop-shaping techniques; for consideration in imple...

This Paper Presents A Method Of Obtaining Optimal Pi Gains For A Fuzzy-Pi Controller To Control The Frequency Of Micro Hydro Power Plant (Mhpp).Conventional Control Techniques Such As Proportional, Integral And Derivative (Pid) Controllers Have Been Used As Controllers To Control The Frequency Of Mhpp, But These Controllers Attain Poor Control Performances, Such As High Overshoots And Long Sett...

This paper presents a hybrid scheme for the control of active and reactive powers using the direct vector control with stator flux orientation (SFO) of the DFIG. The hybrid scheme consists of Fuzzy logic, Reference Signal Tracking (F-RST) controllers. The proposed (F-RST) controller is compared with the classical Proportional-Integral (PI) and the Polynomial (RST) based on the pole placement th...
