In this paper, we investigate the trajectory tracking problem for a fully actuated autonomous underwater vehicle (AUV) that moves in the horizontal plane. External disturbances, control input nonlinearities and model uncertainties are considered in our control design. Based on the dynamics model derived in the discrete-time domain, two neural networks (NNs), including a critic and an action NN, are...
There are different kinds of correlations between sEMG and muscle activities, which can represent the activities of neuromuscular in a certain extent. sEMG is a feeble, complex, non-stationary signal, which is susceptible to external interference. According to these characteristics, sEMG mathematics models of two hand movements (letter `C' in ASL and CSL (ASLC), and extension of index finger (EXIF))...
Wheeled inverted pendulum (WIP) models have been widely used in the field of autonomous robotics and intelligent vehicles. A novel transportation system, WIP-car is proposed in this paper, which is composed of a mobile wheeled inverted pendulum system, a driven chair, an acceleration pedal and a deceleration pedal, which are used to drive the chair forward or backward such that the car can be accelerated...
Through analyzing non-linear, time-varying characteristics of the economic system and summing up the basic idea of nonlinear economic model, BP neural network is used to do non-linear economic modeling methodology and specific implementation steps, by which new ideas is put forward for the existence of model, and implementation of the circumstances in Matlab is given.
