The system interface is a man-machine interface, and its success is directly related to the use of the system. The system interface is shown in Figure 7-1, and the main functions are as follows:(1) Control mode settings, including:Fuzzy control: parameter fuzzy self-tuning PID control. In the fuzzy control mode, the "PID parameter setting" column cannot be selected, that is, the PID parameters cannot be manually input;Manual control: rely on manual input of PID parameters.(2) PID parameter setting: PID parameter setting input can only be used in the manual control mode in the "control mode setting" column.(3) Speed setting and display: set the motor speed.(4) Motion graphics display: the abscissa indicates the position, the ordinate indicates the speed, and the display range can be set through two pink text input boxes.
