| Abstract: | The design and implementation of a simple pendulum with the plate motion control system is accomplished,which is based on the 16-bit microcontroller MC9S12XS128 as the control core,using MMA8452,a 3-axis digital acceleration sensor as a detection module of the system.Angle adjustment of the flat is achieved by using hybrid stepping motor as actuator.For a highly nonlinear stepping motor,a fuzzy PID controller of stepper motor position is designed and implemented.According to the results of the experiment,the controller meets the dynamic and static characteristics of control requirements within a certain range. |
