SHAFT TORQUE CONTROL DEVICE

WIPO Patent Application WO/2018/016628

A1

The purpose of the present invention is to provide a shaft torque control device capable of executing highly responsive shaft-torque control even when the spring rigidity of a connection shaft that connects an engine and a dynamometer to each other varies. The shaft torque control device comprises a feedback control system that includes: a nominal plant Na that imitates input-output characteristics of a test system; a generalized plant Pa that has the nominal plant Na; a controller that provides an input u with use of outputs y1, y2; and a variation term that causes variation in the nominal plant Na on the basis of a variation transfer function, wherein, in the controller included in the feedback control system, setting is made such that a design condition is satisfied. The nominal plant Na is structured on the basis of a two-inertia system configured by connecting two inertia bodies to each other via a shaft having a spring rigidity equal to a predetermined nominal value k0. The nominal value k0 is set to be a lower limit value in an assumed variation range of the spring rigidity of the connection shaft. The variation transfer function is a positive real function, and is set such that said spring rigidity in the nominal plant Na increases from the nominal value k0.
