摘要：In the traditional food transportation tracking loop, the loop gain is generally constant. In order to release the limitation, the adjustment on the optimal loop bandwidth can be applied to achieve high precision food transportation tracking. Aiming at shortening the lock-time of traditional algorithm, this study designed an optimal loop gain algorithm for food transportation tracking loop. By analyzing the loop transient response, the optimal loop gain is designed based on the least lock-time criteria. Since it is unable directly to obtain the numerical solution of the loop gain, a modeling method is developed based on piecewise cubic Hermite interpolation polynomial, in order to achieve the optimal loop gain design in loop under acceptable frequency error. Simulation results show that the proposed algorithm can speed up the loop lock-time. Compared with the constant-gain loop, when the frequency error is 30 Hz, the lock-time of the proposed optimal gain loop is improved at least 46.7%.
