The accelerated acceleration's mutation that exits during the operation of sine function acceleration and deceleration control algorithm is prone to cause flexible impact to the drive system. For this reason, an improved flexible acceleration and deceleration control algorithm is brought forward, which uses cosine function as constructed the acceleration and deceleration function to obtain the mathematical expression of the displacement, velocity, acceleration and accelerated acceleration of the servo motor. The acceleration and deceleration mode is analysed in detail to provide the theoretical basis for the application of the algorithm in the design of the processing curve of servo presses.
