A fuzzy gain scheduling proportional controllers that exhibits the improved performance than the conventional linear fixed gain controller having input saturation is proposed in this paper. We proposed an adaptive anti-windup control system in which the gain of a proportional controller is dynamically tuned by a fuzzy PD system. The methodology employed in the analysis is based on the describin...

Dielectric surfaces exposed to partial discharges (PD) undergo aging, which is reflected by changes in the discharge pulse form. An approach is described in which fuzzy logic and neural networks are used in conjunction with the wavelet transform to identify the parameters in the PD pulse form for the purpose of classifying the aging phenomena due to partial discharge degradation.

Incorporation of parallel mechanisms inside propulsion systems in biomimetic autonomous underwater vehicles (BAUVs) is a novel approach for motion generation. The vehicle to which the studied system implemented presents thunniform locomotion, and its thrust depends mainly on oscillation from caudal fin. This paper describes kinematic dynamic modeling 3-DOF spherical 3UCU-1S robotic fin BAUV att...

Over the past 10 years there has been a growing need to introduce closed-loop control technology for vibration suppression of buildings subject to wind or earthquake disturbances. This paper deals with the investigation of the effectiveness of a fuzzy logic based time variable damping tuned mass damper (TMD) on a building structure undergoing free and forced vibrations. The uniqueness of this a...

onventional linear control schemes often fail to provide C precise positioning of a control object under the influence of friction, deadzone, saturation, etc. This article proposes a highprecision control scheme for a precise point-to-point positioning system, called an X-Y table, even under the above-noted influences. The proposed scheme is composed of a fuzzy precompensator and a PD controlle...

A fuzzy control scheme is proposed for the system of filling and draining off water of the rubber dam(FDWRD) which is a typical nonlinear, multivariables, timevarying and strong coupling control system base on traditional PID control or model-based control methods can not meet its constant flow sufficient drainage control requirements, during to it couldn‘t be established accurate mathematical ...

The classical proportional-derivative (PD) control is relatively easy to design, but useful for fast response controllers by combining proportional control and derivative control in parallel. However, as PD control is linear, it is not able to be used to deal with non-linear plants. An answer to this problem is fuzzy-logic control, which is also a model-free control scheme and can be applied to...

The limitations of conventional model-based control mechanisms for flexible manipulator systems have stimulated the development of intelligent control mechanisms incorporating fuzzy logic and neural networks. Problems have been encountered in applying the traditional PD-, PI-, and PID-type fuzzy controllers to flexible-link manipulators. A PD-PI-type fuzzy controller has been developed where th...

In this paper, a new control method based on FEL electro hydraulic servo control withnonlinear flux and internal friction, has been presented. The new approach based oncontrollers combined by a classic PD controller and a fuzzy controller is smart. This newtechnique has a good ability to control the performance and stability. Simulations have beencarried out in Matlab environment and the result...

In this paper we propose a Self-Organizing Fuzzy Proportional Derivative (SOF-PD) tracking controller for robot manipulators, which exploits the simplicity and robustness of the simple PD control and enhances its benefits. This proposed controller has a gain-scheduling structure, in which, based on the position error, a SOF system performs the gains tuning of a simple PD controller in the feedb...
