PROBLEM TO BE SOLVED: To correct the judgment of the stability/instability of a control system 2 for carrying out the evaluation analysis of the stability of the system by observing a virtual power which flows in this system.;SOLUTION: This control system is provided with: a user control object 3; a user control law 5; a conservative control law H for inputting manipulated variables to the user control object 3 in response to a feedback signal from the user control object 3; and an extended virtual power monitor 10 for observing a virtual power to be virtually transmitted from the conservative control law H to the user control object 3 and the scale of manipulated variables from the conservative control rule and the scale of the output of the user control object. The extended virtual power monitor 10 observes (a) times a virtual power Pν(t), b times a square of the scale of manipulated variables from the conservative control law and -1 times a square of the scale of the output of the user control object. Thus, the evaluation function Ex(t) of stability includes items to be shifted to a stable direction according as the input/output gain of the user control system is made small.;COPYRIGHT: (C)2009,JPO&INPIT
