Put forward a fuzzy control strategy of the magnetic suspension bearing's rotor, and combined with the operating principle of electromagnetic winding, achieve control of the rotor displacement through fuzzy self-tuning PID nonlinear real-time control. Improve the dynamic and static performance of nonlinear systems.
There are more parameters to be analyzed in multiphase motor, in which measurement is more difficult than three-phase equivalents. Parameter variation and load fluctuation in inverter fed multiphase induction machines can bring up the disability and the dynamic property degradation of the control system. In this paper, a fuzzy inference method combining with traditional PID control is utilized to...
In order to change noise problems of the existing gearbox loader, a new type of Permanent magnet loader is designed by using water cooling. The control system is realized mainly by using PLC (Programmable Logic Controller) and MCU (Micro Control Unit), and obtaining signals from multi-sensors. Meanwhile, fuzzy parameters self-tuning PID algorithm and automatic location algorithm have been studied,...
The characteristics of high-frequency and high-speed for high-speed permanent magnet synchronous motor have led to great difficulties for control. The starting and setting is complicated and losing synchronous easily. The current harmonics for the high-speed motor power supply is larger. The high-speed permanent magnet synchronous motor (PMSM) fuzzy-PID controller is proposed in this paper combined...
The fuzzy PID controller is proposed to improve the performance of the network pressure-superposed water supply (NPSWS) system. Taking the pump as the load of the asynchronous motor, the whole system can be simplified as a second-order model. On the basis of the model, fuzzy rules are designed to complete on-line parameters adjustments of PID controller. Comparisons are made between the fuzzy PID...
The severe nonlinearity of translation meshing motor (TMM) make it hard to get a good control performance with conventional proportional-integral-derivative (PID) controller. In this paper, an intelligent PID controller based on fuzzy logic for TMM drive system is developed. The parameters of the proposed controller are tuned online according to fuzzy logic tuning rules which are summarized from the...
This paper presents the development and implementation of a real time hybrid fuzzy-PID control paradigm for an aerodynamic test rig, a twin rotor multi-input-multi-output system (TRMS) which resembles the dynamics of a helicopter in certain aspects. The TRMS can be perceived as a challenging control problem due to its high nonlinearity, the coupling effects between its two axes and the inaccessibility...
A correction factor fuzzy-PID control method is adopted in order to solve the vibration of elevator cab because of the edge effect in the linear elevators driven by the permanent magnet linear synchronous motor (PMLSM). The fuzzy control has the characteristics of being not completely dependent on the mathematics model, but the fuzzy control rules are obtained by experiences of authors or knowledge...
