Title: Reaping height controller in combine harvester
Inventor: KAJIOKA RITSUKO
IPC: A01D34/24
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a reaping height-controlling device in a combine harvester, capable of controlling the reaping height in consideration of not only the counter-ground height but also the extent of the change in a counter-frame elevation position between the reaping pre-treating device of the combine harvester and the travel frame and thereby capable of smoothly and accurately controlling the reaping height, when the reaping pre-treating device is elevated with an elevation hydraulic cylinder 9. SOLUTION: An operation-directed quantity corresponding to a counter-ground height detection value detected with a ultrasonic sensor attached to a reaping pre- treating device is calculated, and an elevation hydraulic cylinder 9 is elevated on the basis of the calculated result. Therein, a counter-frame elevated position is detected with an elevation position sensor 22 disposed between the travel frame and the reaping pre-treating device at a proper sampling timing. The rates of changes in unit time standard counter-frame elevated positions corresponding to operation-directed quantities in a standard work environment are preliminarily memorized.  A correction value for the operation-directed quantity is calculated on a deviation between the standard counter-frame elevation position change rate and a detected counter-frame elevation position change rate calculated for each prescribed timing, and subsequently added to the operation-directed value.

Title: Method for generating ramp function
Inventor: NAGAI TETSUYA
IPC: G05B7/02
Filed: 1988-06-28
Abstract: PURPOSE:To obtain ramp functions in which the time required by output values for reaching changed target values always coincide with set time by using the value obtained by dividing the difference between a target value and output value by the different between set time and elapsed time as the changing rate of the ramp functions. CONSTITUTION:The elapsed time (t) of a timer 26 and the starting value of an integrating section 24 are respectively reset to '0' and the initial value by turning on a reset signal 20. Then updating of the time (t) is started and the time (t) is sent to a changing rate arithmetic section 22 and, at the same time, the integrating operation of the integrating section 24 is actuated by turning off the signal 20. The arithmetic section 22 operates a changing rate K2 from a prescribed expression by using respective inputs values of the time (t), target value y1, set time t1, and output value (y) and the integration section 24 generates the output value (y) of a ramp function by integrating the changing rate K2 time-sequentialy against the initial value y0. Even when the target value y1 and set time t1 are respectively changed to y2 and t2 at a point 1' in the middle of the output, the time required until the output value (y) reaches the value y2 after it is changed can be made coincident with the time t2.
