Abstract:
A method for calculating a future function value associated with an object from derivative values associated with the object, to then control operation of the object, comprising the steps of:providing a sensor coupled to the object for generating derivative values;predetermining a sampling interval T of the derivative values;low pass filtering the derivative values to generate a high frequency value W;acquiring at least one function value from the sensor;determining a value for .tau. by multiplying 2*T*W, wherein 2 is a Nyquist value, and wherein .tau. must always be less than one;computing a which is the solution vector of predictor coefficients in a (N+1).times.1 size matrix in the form a=[a.sub.k.sup.(0), a.sub.1.sup.(1), . . . , a.sub.N.sup.(1) ] for use in a prediction formula, wherein the prediction coefficients are found by minimizing the integral ##EQU21##wherein said prediction formula is in the form of ##EQU22##wherein N=the number of data points,wherein n=an integer 1 to N, andwherein k=an integer 1.ltoreq.k.ltoreq.N used to adjust the calculated result closer to the actual result to generate a future function value f(t); andutilizing the future function value to control operation of the object.
