A novel permanent magnet motor actuator on high voltage circuit breaker is proposed. Based on the characteristics requirement of the circuit breaker, a limited angle permanent magnet brushless DC servo motor actuator is designed. By using the finite element method, the basic characteristics and dynamic simulation of starting are carried out, which the simulation results of the motor (such as electromagnetic...
The linear servo motor drive of high-voltage circuit breaker is designed to realize the opening and closing operation, by which the quicker response ability and the better performance can be obtained. The control system simulation model is developed. Then the hardware of the controller and the control strategy of moving contact based on DSP are designed. Control algorithm of Single neuron PID and...
Starting performance of refrigeration compressors is very important to compressors. The research on starting performance of rolling piston compressors is the research on starting performance of motors actually. An improved starting sheme was proposed in this paper. Simulation and experiment results indicate that the reliability and stability of the starting performance of compressor are improved.
A novel feedback control scheme for speed regulation of permanent magnet synchronous motor (PMSM) is presented based on energy-shaping and port-controlled Hamiltonian (PCH) systems theory. The desired state error port-controlled Hamiltonian structure is assigned to the closed-loop PMSM system by feedback control. Using interconnection and damping assignment passivity-based control (IDA-PBC) methodology,...
To the permanent magnet linear synchronous motor(PMLSM) for vertical hoist system, discontinuous primary PMLSM was adopted. In order to achieve anticipated performances and improved system dynamics, a novel compound control scheme for linear elevator driving by PMLSM with reference model sliding mode control is presented, which integrates advantages of sliding mode control and reference model control...
In order to overcome the parameter uncertainties, enhance the fast tracking performance of PMSM servo system, a self-tuning fuzzy PI+PD controller is proposed first in this paper. The self-tuning fuzzy PI+PD controller is fast; computing on-line easily and can reduce stability error, especially fitting for application in the speed control of the PMSM servo system. Then an observer is adopted to observe...
This paper is concerned with the robust control problem of the permanent magnet synchronous motor (PMSM) chaotic systems with uncertain parameters. Firstly, the T-S fuzzy models with several fuzzy IF-THEN rules are employed to represent the uncertain chaotic PMSM plant. Based on these the T-S fuzzy models, a simple fuzzy controller is designed via PDC technique to realize the stabilization of chaos...
Permanent magnet synchronous motor (PMSM) is a complex plant to control, due to its high nonlinearity and strong coupling. At the same time, the variations of motor parameters make this problem more serious. So, parameter identification of PMSM seems to be important for the double closed-loop vector control system. To solve this problem, a new method combining Elman neural network(Elman NN) and modified...
