The system provides a parameter signal that represents a system parameter indicating oscillation of the object while the stimulus is being applied to the object. The method comprises monitoring maximum amplitude of a dominant tone in a selected frequency band of the parameter signal; and taking an action to avoid imminent control instability if the maximum amplitude persists over a specified period of time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection of imminent control instability","description":"Imminent control instability is detected in a system that applies a stimulus to an object.
