Design of control system of combine harvester louver sieve angle based on ARM

摘要

In view of the disadvantages of the traditional control methods of combine harvester louver sieve, an electronic control system of louver sieve is designed to replace the traditional mechanical regulation structure, and it changes the old way of manipulating louver sieve. In order to achieve the goal control effect more accurately and quickly, the fuzzy adaptive PID control method and the key control design method based on the finite state machine is proposed during the control process. The tests show that the control system can reach louver sieve electric control goals, and can obtain accurate and stable control effect.
