Title:
CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/124044
Kind Code:
A1
Abstract:
The present invention enables the implementations of a normal control of a control device and a safe operation of an object to be controlled. In the present invention, an automatic control unit 10 generates a control output to be output to the object to be controlled in response to an input 1. A safety verification control unit 20 is configured such that the safety of the control output is verifiable at a plurality of verification levels, and outputs the control output on the basis of the verification result. A verification level selection unit 30 manages a state related to the normality of the automatic control unit 10, and selects, according to the state, the verification level of the safety of the control output in the safety verification control unit 20.
