The position of the physical components is detected and used to generate subsequent command signals. In an implementation, an integrity detection system causes an excitation signal to be injected onto the command signal to cause movement of the physical components at an excitation frequency. This movement is detected in the physical system control loop and isolated by the integrity detection system. If the integrity detection system fails to detect energy in the excitation frequency band, a failure of at least one component of the control system is inferred."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for detecting integrity of a control loop of a physical system","description":"In a control loop, a command signal is applied to physical components to cause movement of the physical components.
