This paper focuses on parameter estimation for linear oscillatory actuator (LOA) utilized in linear compressor. A recursive least square (RLS) based method has been developed to estimate the resistance, inductance and thrust coefficient of the motor. Considering the time-varying effect of the system, a forgetting factor is introduced to improve the dynamic tracking precision. A mover displacement...
The use of discrete-event simulation (DES) in the construction and manufacturing industry has been increasing significantly over the past few decades. However, DES at present is mainly utilized during the construction planning phase as a planning tool, and it still remains a challenge to apply simulation during the execution phase for the purpose of construction control without an automated real-time...
Flux-switching permanent magnet linear generator (FSPMLG) has advantages of simple translator structure, and is well suited for the applying for wave energy extraction. In this paper, a gird-unconnected control strategy for FSPMLG based on the vector control and the PI controller is proposed. Firstly, the basic structure of the FSPMLG is introduced. Based on the mathematical models of the FSPMLG,...
The topology of the neural network in brain cortex exhibits small-world characteristics. Excessive synchronization of the brain neuron population is believed to play the crucial role in the emergence of the neuropsychological disorders such as Parkinson's disease and epilepsy, so it is significant to investigate how to eliminate these pathological rhythmic brain activities. A small-world network composed...
The EMS is a typical unstable and nonlinear system. Applying fuzzy controller to it is getting much attention. This paper puts forward the fuzzy control on the EMS based on its prediction model, which has corrected the dynamic instability and eliminated the phenomena of the bigger overshoot or the system oscillation caused by the time-varying of the system, and by adding error weighting coefficient...
