Optimization and Realization of the Coordination Control Strategy for Extended Range Electric Vehicle

open access: yesMachines, 2022
This paper designed a fuzzy adaptive proportional integral differential (PID) control algorithm to optimize the overshoot of speed and torque, fuel consumption and exhaust emissions of the traditional PID control strategy in the process of working ...

A new approach to adaptive fuzzy control: the controller output error method [PDF]

open access: yes, 2002
The controller output error method (COEM) is introduced and applied to the design of adaptive fuzzy control systems. The method employs a gradient descent algorithm to minimize a cost function which is based on the error at the controller output.

Multi-stage hybrid evolutionary algorithm for multiobjective distributed fuzzy flow-shop scheduling problem

open access: yesMathematical Biosciences and Engineering, 2023
In the current global cooperative production mode, the distributed fuzzy flow-shop scheduling problem (DFFSP) has attracted much attention because it takes the uncertain factors in the actual flow-shop scheduling problem into account.

Formalization of Fuzzy Control in Possibility Theory via Rule Extraction

open access: yesIEEE Access, 2019
Possibility system has been recently recognized as a potential foundational theory for fuzzy set theory though the concept of possibility originated from the membership function of fuzzy sets. As an application of fuzzy set theory, fuzzy control has been
