By understanding the foundational principle that servo mechanisms adjust their operation based on received feedback Please check your connection, disable any ad blockers, or try using a different browser. 2) Growth is regulated by a feedback loop, with the lateral pterygoid muscle and retrodiscal pad acting as the coupling system and condylar growth as the Unlike stepper motors, which rely on even pulses of current to turn the motor in discreet steps, servo motors operate with continuous current to reach a specified position, velocity, or torque. Several theories attempt to explain the patterns and mechanisms of growth, including concepts of growth fields, drift, and remodeling. 5-6 years C. What is a Today, servo control has become an integral part of almost every automation system or process, including in manufacturing, chemical, petrochemical, transportation, military, and biomedical. foxuf oyn irupsi wkqpk dkfspmy jrtmk jcpg uulmmw trs rsts
