Evaluating flexible fuzzy controllers via evolution strategies

Fuzzy Sets and Systems, 1999
This paper applies evolution strategies to evaluate a class of flexible fuzzy controllers. Various components in fuzzy controllers, including generalized T-norms, soft T-norm, BADD defuzzification and scaling factors are investigated. Simulations are carried out on linear and nonlinear systems and some interesting conclusions are obtained.

Fuzzy logic strategy on boiler control problem

Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997
In fuzzification problems the shape of the membership function plays an important role. For the application of a fuzzy controller in industry, the TPE system is widely used. The important characteristics of it is that it is straightforward, efficient and independent of the number of rules.

Approximating Fuzzy Control Strategies via CRI

2003
We start from the observation that ZADEH's compositional rule of inference (CRI) is a strategy to determine approximately a roughly given control function. From this point of view the problem to solve a system of fuzzy relation equations also becomes the problem to determine approximately such a control strategy.

Fuzzy avoidance control strategy for redundant manipulators

Engineering Applications of Artificial Intelligence, 1999
This paper presents a systematic design method to solve the problem of obstacle avoidance for a redundant manipulator, using a fuzzy-logic system. The pseudo-distance (Pd) function is introduced to measure the distances between the robot and various obstacles; this function can be effectively solved by linear programming. The traditional implementation

Two fuzzy control strategies of a group

Proceedings of 1995 IEEE International Conference on Fuzzy Systems. The International Joint Conference of the Fourth IEEE International Conference on Fuzzy Systems and The Second International Fuzzy Engineering Symposium, 2002
We propose two fuzzy control strategies for the group behaviour. The first one is a guidance strategy, in which a leader guides a group with attractive forces. The second one is a driving strategy in which the members of a group moves with their repulsive forces and the repulsive forces from the leader of the group.

A new adaptive fuzzy nonlinear control strategy

IEEE. APCCAS 1998. 1998 IEEE Asia-Pacific Conference on Circuits and Systems. Microelectronics and Integrating Systems. Proceedings (Cat. No.98EX242), 2002
This paper proposes a new adaptive fuzzy nonlinear control strategy that allows designers to systematically construct fuzzy control. The control strategy proposes the use of fuzzy logic systems within a well understood control structure that is called nonlinear internal model control (NIMC) structure.

Study on Fuzzy PI Control Strategies of Networked Control System

Advanced Materials Research, 2013
When using a remote networked control system, a network-induced time-delay is generated, which causes advert effects on the closed-loop networked control system such as performance degradation and system destabilization. For solving the time-delay in remote control system, intelligent fuzzy logic compensator is introduced in this paper to improve the ...

MPPT control strategy for photovoltaic cells based on fuzzy control

2016 12th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD), 2016
As output of photovoltaic batteries varies following the change to illumination, temperature and loads, it is necessary to do some researches on new control method of Maximum Power Point Tracking (MPPT) to guarantee high-efficiency output of photovoltaic batteries.

Design of Rectifying Controller Based on Fuzzy PID Control Strategy

2020
Strip offset can cause registration errors, resulting in a large amount of waste during the printing process. In order to achieve precise control of the running track, this paper designs a correction system controller based on fuzzy PID control strategy.

Control strategy in hybrid electric vehicle using fuzzy logic controller

2009 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2009
In a hybrid vehicle with dual power systems such as internal combustion engines working with conventional fuels and electric motors, each system has specific operational characteristics and requirements which these have to be matched with each other and at the same time with the vehicle itself.
