In the present work, artificial neural network (ANN) has been used to identify a servo-driven inverted pendulum system. The inverted pendulum is a benchmark problem of nonlinear multivariable system with inherent instability. The multi variable system has been considered with servomotor supply voltage as the input and four states of the system being the outputs. An LSVF controller has been used to...
The performance improvement of hydraulic simulator is effected by dynamic nonlinear friction. A nonlinear adaptive frication compensation method based on LuGre friction model is proposed to acquire good low-speed performance of hydraulic simulator after analyzing dynamic friction of hydraulic simulator and building LuGre friction model of hydraulic simulator. Dual nonlinear observers are constructed...
This paper addressed the model of the four-degree-of-freedom control system of SMT. Undesirable uncertainties are introduced and considered to improve the proposed model. Experiments, simulations and analysis give more understanding in this model.
