Abstract:

In order to ensure the real-time performance and accuracy of the acceleration and deceleration algorithm in the motion control system of the cutting machine, the traditional acceleration and deceleration algorithm is not easy to determine the deceleration point. In order to ensure the accuracy of the acceleration and deceleration algorithm in the motion control system of the cutting machine, the proposed trapezoidal acceleration and deceleration algorithm based on FPGA (Field Programmable Gate Array) is compared and analysed with the commonly used acceleration and deceleration algorithms, and the Vivado simulation system is used to simulate and build an experimental platform to verify the algorithm. The experimental results show that the improved trapezoidal acceleration/deceleration algorithm can automatically determine the position of the deceleration point and meet the requirements of real-time, and the comparison between the ideal curve and the actual curve shows that the actual running speed curve of the motor is smooth and the speed error is small.
