This paper studies the identification problems of input nonlinear controlled autoregressive moving average (IN-CARMA) systems, and derived an auxiliary model based recursive extended least squares (AM-RELS) algorithm and a maximum likelihood algorithm based on the Newton optimization method. The simulation results show that the proposed algorithm are effective.
A variable structure neural network control (VSNNC) is proposed for a class of uncertain nonlinear SISO systems, in which neural network is used as an estimator for the system unknown nonlinear functions. And variable structure control strategy is improved by adding the continuous function item to control input. It can adjust discontinuous item in control variable adaptively according to the distance...
Variable structure control (VSC) theory is applied to analyze and design AC servo system for field-oriented permanent-magnet synchronous motor, which is based on Luenberger load observer. Some results of simulation experiments suggest that the AC servo system based on VSC has speedy response, high accuracy and strong robustness against its parameter variations and load disturbances. Its performance...
A new structure of tunneling gyroscope which is high-accuracy and low-range was presented in this paper, as well as the structure and the operating principles of this gyroscope were analyzed. Besides, the simulations were made in this paper which is close to the principle. Then the structure was fabricated by MEMS technological processes. And its tunneling effect was tested by HP4156C high precise...
