MODEL BASE CONTROL DEVICE AND DESIGN METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a model base control device for controlling a control object including a waste time between input and output, which can accurately control the control object by two-degree-of-freedom control.;SOLUTION: An FF controller 20 is constituted by a reverse model P'^-1 with no waste time simulating a relation established between output Y and input X of the control object in the absence of waste time. A time controller 24 is constituted by a normal model P'e^-sT with waste time sumilating a transmission function actually established between the input X and the output Y. An output target value Y_T of the control object 12 is supplied to the reverse model P'^-1 with no waste time to calculate an input basic value X_B. The input basic value X_B is supplied to the normal model P'e^-sT with waste time to calculate an output prediction value Y'. An FB correction quantity ΔX is calculated so as to extinguish the difference ΔY between the output prediction value Y' and the actual output Y, and the input X is corrected with the resulting value.;COPYRIGHT: (C)2006,JPO&NCIPI
