Title:
RISE AND FALL CONTROL DEVICE OF WORKING TREATING PART IN MOBILE AGRICULTURAL MACHINE
Document Type and Number:
Japanese Patent JP3216654
Kind Code:
B2
Abstract:
PURPOSE: To simultaneously attain improvement in response to the control of rise and fall of operation treating part in mobile agricultural machine and prevention of hunting.
CONSTITUTION: Detected height of an ultrasonic sensor 8 from the surface of the ground is read (S1) at each given time and a deviation E of the detected height from a desired set value preset before the operation and a changed part ΔS of the deviation E with time are calculated (S2). Then, a handled amount HB of a hydraulic cylinder 6 is determined (S3) from the calculated deviation E and the changed part ΔS of the deviation E with time by the fuzzy control rule. The hydraulic cylinder 6 is handled (S4) based on the determined amount HB.
