Title:
CONTROL METHOD AND CONTROL SYSTEM FOR ROTATION SPEED OF ROTARY TABLE, AND AERIAL WORK PLATFORM
Document Type and Number:
WIPO Patent Application WO/2023/061385
Kind Code:
A1
Abstract:
A control method and control system for the rotation speed of a rotary table, and an aerial work platform. The control method for the rotation speed of a rotary table comprises: when an arm support is in an unfolded state, if the amplitude change angle α of the arm support satisfies α ≥ α0, and the length L of the arm support satisfies L < L0, the rotation angular speed ω of a rotary table satisfying ω = ω0 - k1(α - α0), wherein α0 is a set constant of the amplitude change angle of the arm support, L0 is a set constant of the length of the arm support, and k1 is an amplitude change control angular speed coefficient of the arm support; if the amplitude change angle α of the arm support satisfies α <α0, and the length L of the arm support satisfies L ≥ L0, the rotation angular speed ω of the rotary table satisfying ω = ω0 - k2(L - L0), wherein k2 is an elongation control angular speed coefficient of the arm support; and if the amplitude change angle α of the arm support satisfies α ≥ α0, and the length L of the arm support satisfies L ≥ L0, the rotation angular speed ω of the rotary table satisfying ω = MIN{ω0 - k1(α - α0), ω0 - k2(L - L0)}. The control system comprises a computer-readable storage medium and a control unit, and the aerial work platform comprises the control system.
