Abstract: In a service providing system, a first database holds plural kinds of balloon data, in which each of plural pieces of three-dimensional real space range information and an identifier for identifying the three-dimensional real space range information is related, and a second database holds a service execution file in which each of plural pieces of three-dimensional space region information related to each identifier and service information in each three-dimensional space region are related. An extracting unit extracts, using position on a user terminal and an identifier, a service execution file corresponding to a three-dimensional space region. A service execution processing unit performs an executing process of a service corresponding to service information held in the extracted service execution file. The service system provides various kinds of services information at any time, effectively use the hardware, and limit the access. The user obtains service information available in a wide area.

Abstract: A control system is designed in which a controlled plant is controlled based on output feedback from the controlled plant. An all-pass filter is modeled that is formed of a synthesis of a notch filter compensating for a resonance mode in the control system and the resonance mode. A design controlled plant including the all-pass filter is determined. A controller controls the design controlled plant and includes a weighting function, and, after the weighting function is derived, gain of the weighting function is adjusted using desired gain crossover frequency and phase margin. A phase variable included in a phase-lead weight is determined, and thus the weighting function is determined. H? loop shaping is applied to the weighting function and the design controlled plant to obtain an H? loop controller.
