The six-degree platform control system is the electrical control part of the six-degree platform. It realizes the position and attitude control of the platform through the real-time closed-loop control of the six-way hydraulic cylinder. The control system uses NI computer and configures various types of PXI board, realizes the control of voltage, current, digital IO, CAN bus and other interface types of the platform, meets the reliability requirements. Typical upper and lower computer control is adopted to carry out real-time calculation and task management respectively, which solves the real-time requirements. Labview is used to develop the measurement and control software, which completes the forward and reverse module of the real-time computing platform and the closed-loop control of the actuator, so as to enhance the function and flexibility of the system. At present, the hardware and software of the six-degree platform measurement and control system have passed the debugging. The sinusoidal motion and transient characteristics of the system have been tested. The experimental results show that the system runs fast and meets the control requirements of the platform.
