Title:
CONTROL SYSTEM, AND INERTIAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/145484
Kind Code:
A1
Abstract:
The present invention improves attitude detection accuracy in a control system that employs a plurality of inertial sensors. A control system (1) comprises a first inertial sensor (10), a second inertial sensor (20), a first signal path (30), and a second signal path (40). The first inertial sensor (10) includes first to third angular velocity detecting elements, first to third acceleration detecting elements, and a first control unit. The first control unit calculates a first attitude signal. The second inertial sensor (20) includes fourth to sixth angular velocity detecting elements, fourth to sixth acceleration detecting elements, and a second control unit. The second control unit calculates a second attitude signal. The first control unit calculates first detection axis information on the basis of the first attitude signal and the second attitude signal, and generates a first reference signal from at least either of the fourth to sixth angular velocity signals and the fourth to sixth acceleration signals. The first control unit additionally generates a first corrected signal by employing the first reference signal to correct at least either of the first to third angular velocity signals and the first to third acceleration signals.
