An Adaptive PD-Type FLC and Its Real Time Implementation to Overhead Crane Control
نویسنده
چکیده
In this study, we proposed an Adaptive Fuzzy PD Controller (AFPDC), where output gain is adjusted, based on the current operating condition of the process, by an online updating parameter (β) that is calculated by normalized error (eN) and normalized change of error (ΔeN) of the process. The proposed controller is tested on second-order process models including an unstable system. Comparative performance analysis is provided with fuzzy and conventional controllers in terms of several performance indices. Finally, the proposed control approach is investigated on a practical overhead crane to control its cart position as well as swing angle of load. The proposed self-tuning control scheme shows an accurate transfer of load, along with a good swing suppression.

A New Implementation of Maximum Power Point Tracking Based on Fuzzy Logic Algorithm for Solar Photovoltaic System
In this paper, we present a modeling and implementation of new control schemes for an isolated photovoltaic (PV) using a fuzzy logic controller (FLC). The PV system is connected to a load through a DC-DC boost converter. The FLC controller provides the appropriate duty cycle (D) to the DC-DC converter for the PV system to generate maximum power. Using FLC controller block in MATLABTM/Simulink e...

متن کاملAnti-Swing Control For An Overhead Crane With Fuzzy Compensation
This paper proposes a novel anti-swing control strategy for an overhead crane. The controller includes both position regulation and anti-swing control. Since the crane model is not exactly known, fuzzy rules are used to compensate friction, gravity as well as the coupling between position and anti-swing control. A high-gain observer is introduced to estimate the joint velocities to realize PD c...
متن کاملAnti-swing Fuzzy Controller Design for a 3D Overhead Crane
This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...
