Abstract

PURPOSE:To effectively actuate the plant adaptive control in an on-line system by calculating the optimum gain after estimating both transmission and disturbance matrices of a plant from the probable irregular signal. CONSTITUTION:Both A and S matrices of a plant are estimated from the arithmetic data on the power spectrum density of a probable irregular signal omegan and the optimum gain is variably switched. In other words, the signal omegan is measured in a prescribed cycle and the trend is deleted for each measurement of the signal omegan together with calculation of the auto-correlation function and the power spectrum density. Then the data on the power spectrum density of a prescribed frequency is optionally extracted at the observing point of each power spectrum density. An approximate function of the power spectrum density is obtained by a nonlinear parameter estimating method and converted into a molding filter having a certain delay for acquisition of the gain and a time constant of the filter. Then the elements of the transmission matrix A and the disturbance matrix S are rearranged based on the molding filter. Thus the optimum gains are calculated in each prescribed cycle and the optimum gain following the characteristics of the signal omegan is decided. In such a way, the adaptive control of the plant is carried out in an on-line system.
