On the basis of hyperstable theory and adaptive inverse control theory, a new adaptive control algorithm of overcoming the subject disturbance was proposed.
Software subdivision and "virtual frequency conversion" technology were adopted in this solution, which realized multigrade, adaptive subdivided drive in operation of stepping motor.
On the basis of the adaptive inverse control and the hyperstable theory, a method of designing discrete MRAC, which overcomes random disturbance, is proposed.
Numerical simulation studies indicate that the adaptive filter is a powerful noise suppresser for correlated interferences, especially for those with amplitude changing and time delay.
At the same time, a new clutterlock algorithm of proportion factor self-adaptive in image field is introduced, which can improve the converging speed and the precision of result.
A new variable step-size LMS adaptive filtering algorithm is presented, which makes use of the intercorrelation function of the relative output error signal to control the new variable step-size.
