Semi-physical simulation platform with multi-mode switching function

The invention relates to a semi-physical simulation platform with a multi-mode switching function, which comprises a physical part and a virtual part, the physical part comprises a physical control system, a physical hydraulic system, a physical sensor and a physical loading system, and the virtual part comprises a virtual control system, a virtual hydraulic system, a virtual sensor and a virtual loading system. State quantities in the physical part and the virtual part are transmitted to the computer through the physical sensor and the virtual sensor respectively, the computer controls the semi-physical simulation platform to simulate the controllable-pitch propeller electro-hydraulic system in four different modes, and the physical loading system and the virtual loading system provide loads for the semi-physical simulation platform. The semi-physical simulation platform can operate normally. The semi-physical simulation technology is used, the research and development cycle of the controllable-pitch propell
