Application of Analog Control in Correction System
What are the main aspects of the corrective controller used in the field of fuzzy control? It mainly includes the following four aspects:
1. Fuzzy Correction Controller - The fuzzy controller part mainly includes three parts: fuzzy, fuzzy control rules and fuzzy elimination. The fuzzy controller uses Cortex-A9 microcontroller.
2. Correction control actuator - The actuator selected by the domestic SE-150 correction actuator (also known as the correction drive), as a brushless DC motor with superior performance, its maximum speed can reach 40mm / s.
3. Corrected control object - The controlled object of the corrective controller is not only the coil material, but also receives the non-control force under the high speed condition, and can not keep the straight line running and the center line of the width is deviated from the reference center line.
4. Correction Sensor - This device uses the ultrasonic correction sensor AE-210 to perform high-resolution ultrasonic sensing/frequency conversion and directly communicate with micro processing.
The whole rectification control process is to sample the photoelectric rectification sensor through the single-chip microcomputer, and to blur the data after processing, to analyze the relative deviation of the controlled object, query the fuzzy control rule table, select the corresponding control strategy, and send it to the actuator driving motor. Correction.
