Method for automatically setting controller bandwidth


Robustly stabilizing controller bandwidth for a controlled mechanical system is determined as a function of the system's estimated inertia and dominant system parameters that define constraints on the bandwidth. In one or more embodiments, a bandwidth model is derived that defines a relationship between robustly stabilizing controller bandwidth and system gain over a range of reasonable system uncertainties.

Vehicle seat and manufacturing the same


There is provided a method of manufacturing a vehicle seat configured by covering a seat cover on a sitting surface side of a seat frame via a seat pad and by covering a non-sitting surface side of the seat frame with a carpet, the vehicle seat including an end fixing part having a groove into which both ends of the seat cover and the carpet are to be inserted and fixed. The method includes fixing, to the end of the seat cover, an insertion member having stiffness, which can be inserted and fixed in the groove integrally with the seat cover, arranging the carpet such that the end thereof covers an entrance of the groove, and inserting the insertion member into the groove to thus push and fix the end of the carpet in the groove while the end of the carpet abuts on the insertion member..
