Title:
LEARNING CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPH0546206
Kind Code:
A
Abstract:
PURPOSE:To perform the high precise follow-up action by correcting a control input so that the weighted squares sum of the predicted value of a future deviation can be minimum and considering the future correction quantity then. CONSTITUTION:A trial is repeated so as to follow the output of a control object to a target command to repeat the same pattern, and a control input uk(i) at time (i) for the k-th trial is given by an expression I. In the expression I, sigmak(i) is a correction quantity from a previous control input uk-1, sigmap(i) is a correction quantity inputted until reaching the present time, eL(i) is a follow-up deviation at the previous trail, wh1 is the information concerning the dynamic characteristic of the controlled variable and a constant decided by the weighted matrix multiplied to the predicted value of the future follow-up deviation, HF and HP are the constant decided by the information concerning the dynamic characteristic of the controlled variable and W is the weighted matrix multiplied to the predicted value of the future follow-up deviation.
