Hardware-in-Loop Test of Rotary Steerable System Main Controller

To solve many problems faced by the main controller of the rotary steerable tool in the actual test, such as time-consuming, poor economy, difficulty in building a test environment, and it is not easy to arbitrarily change the measurement variables according to the test requirements. By making the simulation attitude sensor model and the mud downlink command model, downloading it into the rapid prototyping controller SP6000, and adding the corresponding I/O interface between simulation and semi-physical simulation, the virtual attitude sensor and mud downlink command simulator are designed. And then combined with the permanent magnet synchronous motor to perform the hardware-in-loop test of the main controller of the rotary steerable tool. This test can meet the requirements for different attitude angle parameters and mud down commands during the main controller test. After the experimental trial, the test system solves the problem of difficulty in setting up the test on the one hand. On the other hand, the measurement variable can be arbitrarily changed according to the test requirements, which significantly saves the tester's time and improves the test efficiency.
