Title:
NONLINEAR CONTROLLER
Document Type and Number:
Japanese Patent JP2686391
Kind Code:
B2
Abstract:
PURPOSE: To control a nonlinear system whose control model is unknown without requiring any mass-storage memory for storing a generated algorithm by developing the algorithm which can generate a simple model with high usability as a control rule in a short time.
CONSTITUTION: While the modeling algorithm which normalizes data showing the input/output relation of a controlled system, analyzes the normalized data by a method for fuzzy qualification II, etc., and approximating the characteristic distribution obtained by the analysis to a function is stored in storage parts 12, 13, and 14, a calculation procedure based upon the function which approximates the input/output relation obtained by the algorithm is stored in a storage part 15. A CPU 11a executes the modeling algorithm and a CPU 11b operates the output corresponding to the input from a controlled system according to the calculation procedure and outputs the arithmetic result as a control signal.
