The gain adjusting unit uses the reference frequency characteristics and actually measured frequency characteristics to calculate an evaluation function value for each frequency sweep, and adjusts online the speed control loop gain to achieve a desired evaluation function value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Servo control apparatus having function of optimizing control gain online using evaluation function","description":"A servo control apparatus includes a speed command generation unit, a torque command generation unit, a speed detection unit, a speed control loop, a speed control loop gain setting unit, a sinusoidal","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9703273","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
