This paper describes the implementation of the temperature control system for sintering shaft furnace. In order to solve the problems caused by pure time-delay and non-linearity, an intelligent serial temperature control system is introduced in this paper, where the fuzzy controller is used in the main control loop and the fuzzy neural network PID controller is adopted in auxiliary loop. Simula...

The texture of rotary-veneer can interference in defects detection, this paper presented a modified semi-fuzzy clustering (SFC) algorithm. SFC algorithm incorporates Fisher discrimination method with fuzzy theory using fuzzy scatter matrix. By iteratively optimizing the fuzzy Fisher criterion function, the final clustering results are obtained. SFC algorithm exhibits its robustness and capabili...

This paper presents the design of a fuzzy-controller-based ultra-high vacuum pressure control system and its performance evaluation for sputter-ion pump used in electron storage ring at Synchrotron Light Research Institute (Public Organization) Thailand. The production synchrotron light requires advanced technology to maintain stability prevent interference electrons an environment about 10−9 T...

chickpea (cicer arietinum) is the third most important pulse crop in the world, grown widely across asia and the middle east. weed is one of the main limiting factors in chickpea (cicer arietinum) production. several characteristics of chickpea (cicer arietinum), such as slow plant emergence, short plant height, and chickpea morphology allow weeds to compete effectively. to investigate the effe...

A robust Sugeno type adaptive fuzzy neural network (RSAFNN) backstepping control for a two-axis motion control system is proposed in this paper. The adopted two-axis motion control system is composed of two permanent magnet linear synchronous motors (PMLSMs). The single-axis motion dynamics with the introduction of a lumped uncertainty, which includes parameter variations, external disturbances...

In this paper, a fuzzy adaptive linear active disturbance rejection control (Fuzzy-LADRC) is proposed for strong coupling and nonlinear quadrotor unmanned aerial vehicle (UAV). At present, UAV conveys new opportunities in the industry, such as power line inspection, petroleum conduit patrolling, defects detection wind turbine, because of its advantages flexibility, high efficiency, economy. Usu...

This paper studies the electro-hydraulic proportional position control system of a hydraulic rock drilling jumbo. First all, composition is introduced and transfer function components established, mathematical model whole finally obtained through calculation simplification. Then, PID fuzzy strategy were designed by MATLAB software, was built in simulink. Finally, results indicate that controlle...

In this paper, new definitions of $L$-fuzzy closure operator, $L$-fuzzy interior operator, $L$-fuzzy remote neighborhood system, $L$-fuzzy neighborhood system and $L$-fuzzy quasi-coincident neighborhood system are proposed. It is proved that the category of $L$-fuzzy closure spaces, the category of $L$-fuzzy interior spaces, the category of $L$-fuzzy remote neighborhood spaces, the category of ...
