Claim 8:
9. The ground testing device for a stabilized platform of a rotary steerable drilling tool according to claim 5, wherein the main controller comprises:
the stabilized platform controller configured to: directly send the received direct current bus voltage set value V* to the bus voltage controller, directly send the received tool face angle set value φ* to the tool face angle controller, and send the measurement data of the upper current sensor to the rotating speed controller as a correction amount;
the bus voltage controller configured to: dynamically adjust the current set value of the upper turbine generator driving controller according to the set value V* and the measurement data of the voltage sensor so as to adjust the electromagnetic torque of the upper turbine generator;
the tool face angle controller configured to: dynamically adjust the set value of the rotating speed controller according to φ* and the tool face angle measurement value obtained by means of the tool face angle measurement unit; and
the rotating speed controller configured to: dynamically adjust the current set value of the lower turbine generator driving controller according to the rotating speed set value, a measurement value of the rotating speed sensor, a measurement value of the lower current sensor, and the correction amount of the rotating speed controller so as to adjust the electromagnetic torque of the lower turbine generator.
