The table may be a two- or three-dimensional table additionally responsive to the current system state, such as shaft speed, position, or phase angle. The motor may be a two-coil stepper motor where the corrected non-linearity serves the purpose of maintaining desired toque. Inputs may be waypoints comprising both a target position and target velocity. The motion system may use an inverted SCARA arm. Up to three non-linear correction tables may be used: a first corrects motor steps to a more accurate shaft angle; a second corrects motor drive signals to achieve desired torque; a third correct motor drive signals responsive to shaft speed. Tables may be generated by a series of motion passes using a fixed shaft offset angle for each pass."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and method of motion control","description":"A device and method of iterative motion control is described using a non-linear table in a feedback loop to convert a desired acceleration input to motor drive outputs, where the motor is part of a co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10488842","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.
