Universal test bench of diesel hydraulic governor based on hardware-in-loop simulation

The universal test bench for diesel hydraulic governor using hardware-in-loop simulation technology is established. The problems of common in use, variable-speed drive, simulation model, data acquisition and analyzing are solved. The structure of the test bench, along with the hardware and software meeting the requirement of deterministic real-time performance are introduced. Some experimental results are provided to prove the effect of the test bench, which providing a facility for a technician to conduct a general check and calibration for governor assembly.
