Title: Method for controlling learning
Inventor: KAWAI SEIJI
IPC: G05B19/42
Filed: 1989-05-10
Abstract: PURPOSE:To allow the method to apply 'different target value changing patterns' by storing the control outputs and control deviations for representative patterns and extracting a pattern most similar to a given operation pattern to learn the evaluation of a control result. CONSTITUTION:When a current target value changing pattern is provided, an evaluation function is calculated from target value changing patterns stored in the past and a pattern having the minimum evaluation function is defined as the most similar target value changing pattern. The control output of the provided target value changing pattern is computed by using the practical control output value and process variable corresponding to the selected target value changing pattern. The sum of square means of deviations is found out at the time of finishing the target value change, and if the current target value changing pattern is more excellent than the selected one, the current target value changing pattern, control output value and process variable value are substituted for the selected ones. Thus, learning control utilizing the past similar pattern for different target value changing patterns can be attained.
