The invention discloses a multi-
actuator cylinder cooperative control device and control method. By the aid of the method, a plurality of
actuator cylinders can be controlled by a flight
control unit and a
remote control unit or an operating rod to collaboratively make telescopic movement, switching can be conducted conveniently between two control
modes, each set of control loop has the two protecting
modes of
software limiting and hardware limiting, the
actuator cylinders can be prevented from stretching beyond a limited movement range, and thus an actuator cannot be clamped; when a
normal control mode loses
efficacy, the device can be timely switched to be in an
emergency control mode, an emergency loop is composed of an independent
relay set, and thus normal movement of the actuator can be guaranteed when the
normal control mode loses
efficacy. By means of the multi-actuator cylinder cooperative control device and control method, the defects that a traditional single-actuator cylinder controller is large in size, manual operating rod signals and
remote control unit signals are not compatible, and the control movements of multiple actuator cylinders are not consistent are overcome, the
moving speed and the moving range of each actuator cylinder can be controlled through
software, and the control precision and the flexibility of the control device are improved.
