Abstract
PURPOSE: To smoothly correct the angle of a bucket by turning the bucket by an angular velocity based on signals obtained by adding control velocity signals from the angular velocities of boom and arm to angle-deviation signals from the angles of boom and arm.
CONSTITUTION: In a method of controlling the angle of a bucket under this invention, in order to keep the absolute angle θ of the bucket 4 constant when a boom 2 and an arm 3 are operated, control velocity signal -α'-β'≡γγ' is obtained from the angular velocity signals α' and β' of the boom 2 and the arm 3, and the bucket 4 is turned by an angular velocity based on the control velocity signal γγ' to perform an open loop control. And, in the method of controlling the angle of the bucket under this invention, a position feedback control based on an angle-deviation signal Δγ is also made. Thus, the control of the bucket can be performed with good response, and variations in the absolute angle due to external disturbance, etc., can also be corrected by feedback control.
