The invention provides a motion platform for analog
simulation and a control method thereof. The motion platform comprises a base, a first motion platform, a second motion platform and a
control system. The first motion platform and the second motion platform are arranged on the base in a stacked mode, each of the first motion platform and the second motion platform is driven by an
independent motion mechanism, and motion decoupling is achieved. The first movement platform serves as a middle platform and is connected with the base through the three first movement mechanisms. The second motion platform serves as an upper platform and is connected with the first motion platform through three second motion mechanisms. The
control system can control operation of the first movement mechanism and / or the second movement mechanism, so that the position and angle of the first movement platform and / or the second movement platform are changed, and multi-
pose simulation is achieved. According to the motion platform, the three-degree-of-freedom design of double-platform superposition is adopted, the structural form is simple, few computing resources are consumed in the settlement control process, and the control precision and efficiency are high.
