This paper analyzes the number of operations and parameters of general fuzzy logic control algorithms. And limitations of loop controllers to implement the fuzzy logic control are investigated in terms of computation time and required memory. Using analysis of general fuzzy logic control algorithms, it is shown that general fuzzy logic control algorithms are not suitable for loop controllers. A...

In this paper a new technique for monitoring shifts in covariance matrices of Gaussian processes is developed. The processes we monitor are obtained from the covariance matrices estimated using a single observation. These processes follow independent Gaussian distribution in the in-control state, thus allowing for application of standard control charts. Furthermore, in contrary to the existing ...

In this paper a fuzzy logic scheme is applied for direct torque fuzzy control (DTFC) of five phase induction machine (FPIM). The proposed DTFC based on fuzzy logic technique switching table is described and compared with conventional direct torque control (DTC). The proposed fuzzy control strategy is simulated using Matlab/Simulink software. The simulation results show that DTFC method reduces ...

This paper presents the design and implementation of an integrated fuzzy logic controller (IFLC) for a high-speed permanent magnet DC (PMDC) motor speed control system. The proposed strategy is intended to improve the performance of the conventional controller by use of IFLC. The system is studied for step input with and without load (magnetic) conditions and for various standard input test com...

Agriculture in Russia has some specifics such as large distribution, inclement climate and big market competition. Appearing of resources-economy, precision and management technologies demanded from agriculture companies new planning and control methods. The paper is dedicated to assembly charts planning in agriculture with multi-agent approach. For resources distribution we used method of virt...

Abstract: In this paper, conditions of the chaos in auto gauge control system are suggested and proved on the basis of the roll eccentricity model. It is proposed that the eccentricity disturbance of roll may cause chaotic phenomena in the rolling process. By analyzing four kinds of expandable and shrinkable factors of variable universe fuzzy controller, it is suggested that the contradiction b...

Because of the low maintenance and robustness induction motors have many applications in the industries. Most of these applications need fast and smart speed control system. This paper introduces a smart speed control system for induction motor using fuzzy Sliding mode controller. The fuzzy-logic with sliding mode speed controller is employed in the outer loop. The performance of Fuzzy Logic co...
