The invention discloses an unmanned double-propeller ship propulsion controller suitable for a brushless direct current motor. The controller comprises a control module taking a DSP (Digital Signal Processor) as a core, wherein the control module taking the DSP as the core is respectively connected with an optocoupler isolation module, a detection module and a communication module; the optocouplerisolation module isolates a control signal between the control module taking the DSP as the core and the driving module, the control module performs power amplification on a PWM signal and then is connected to the three-phase full-bridge inversion module, and the three-phase full-bridge inversion module receives the driving signal of the driving module and controls the brushless direct current motor; the detection module is connected with the motor assembly and used for position detection, rotating speed detection and bus current and motor phase current detection; the communication module performs information interaction with the unmanned ship controller; and the power supply module supplies power to other modules. According to the controller, reliability and the anti-interference capability of the motor controller are improved, and the cost is reduced.
