  • Patent number: 5267139
    Abstract: In an improved Parameter Estimator/Identifier for identifying unknown constant parameters in signal processes and/or dynamical systems, such as used in Adaptive Control Systems in systems engineering and in Time-Series Analysis and Prediction in econometrics, biomedical signal analysis, operations research, sonar/radar/optics data processing systems, and resource allocation, the ZEE (Zero Error Equilibrium) convergence quality improvement comprising replacement of negative feedback of the signal estimate error by a non-singular multiple of the ID estimate error, which is equivalent to minimizing the integral of the square of the instantaneous signal estimate error by means of negative feedback of its gradient with respect to the unknown parameters to affect the rate of change of the estimation/identification process, thereby rendering dithering or artificial maneuvering or stochastic excitation or broadband harmonic excitation of the input (hence also the "carrier" or regressor) unnecessary and eliminating th
