Embodiment Construction
[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] The invention provides a high-precision servo system, such as figure 2 As shown, it can be detailed as follows:
[0020] The system initialization module is executed from the power-on of the program, involving all registers, global variables, macro definitions, structures, flags, counting variables, PID parameters, motor position initial parameters, and various output data limit value settings used by the program. And peripheral clock control registers, GPIO registers, VPIF, PSC, UART for initialization configuration.
[0021] After the system initialization is completed, the system enters the interrupt service program, reads the current position of the azimuth and pitch motors sent by the absolute encoder 4, and the serv...
