The threshold control theory is applied to build a physiology-based FES controller. The proposed control strategy is tested in simulation study with an integrated musculoskeletal model. The results suggest that the controller based on the threshold control theory alone can realize the task with small feedback delays. However, it is not capable to produce the movement fast enough to match the desired...
An EEG integrated analysis system was developed by LabVIEW, which expanded bandwidth above 3 (KHz) to collect more useful information. The novel bandwidth preamplifier was designed and the system of data acquisition, integrated analysis was implemented, which could analyze EEG with an optional combination of time domain, frequency domain, time-frequency, nonlinearity, chaotics, several spectral analysis,...
Epilepsy is a group of disorders characterized by recurrent paroxysmal electrical discharges of the cerebral cortex that result in intermitted disturbances of brain function. The damage induced by seizure is severe, so it is significant to predict the preictal state of the epileptic seizure. The aim of this work is to compare and estimate the different nonlinear analysis methods in predicting of epileptic...
Epilepsy is a brain dysfunction disease, which is caused by brain neuron excessive discharge. The damage induced by seizure is irreversible, so it is necessary to propose a new method to prevent epileptic seizure and protect the brain. Therefore, the best way is to predict preictal state accurately and to give preventive treatment. In this paper, the calculation of the largest Lyapunov exponent based...
In control, stability insures the reproducibility of motions and the robustness to external and internal perturbations. In this short paper, the stability of the λ-model during fast elbow movements are analyzed, and the operation regions of the unmeasurably descending commands are calculated to guarantee the stabilizing ability of the motor control system. In this system, the elbow is modeled as a...
