Abstract
A load control method and a load control system of an indenter based on fuzzy predictive control, are provided. The method includes acquiring an actual measured force value of a sensor and an expected force value of the nth cycle in the loading stage; calculating a first error and a change rate; establishing and optimizing a fuzzy predictive controller; determining movement steps of a motor in the loading stage; acquiring the actual measured value of the sensor and an expected force value of the nth cycle in the full load stage; controlling the movement of the motor; acquiring the actual measured force value of the sensor and an expected force value of the nth cycle in the unloading stage; calculating a third error and a change rate; and determining the movement steps of the motor in the unloading stage.
