摘要：
A method of adjusting velocity in a motorized surgical instrument is provided. The surgical instrument comprises a displacement member configured to translate within the surgical instrument over a plurality of predefined zones, a motor coupled to the displacement member to translate the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, the position sensor configured to measure the position of the displacement member and a timer circuit coupled to the control circuit, the timer circuit configured to measure elapsed time. The method includes setting a directed velocity of the displacement member； determining an actual velocity of the displacement member； determining an error between the directed velocity of the displacement member and the actual velocity of the displacement member； and controlling the actual velocity of the displacement member based on the magnitude of the error.
