The invention aims to provide a cooperative control method for a hybrid intelligent power generation unit of a ship, which comprises an ammonia fuel engine and a three-phase permanent magnet synchronous motor, the ammonia fuel engine adopts throttle torque control, and the three-phase permanent magnet synchronous motor adopts rotating speed control; a feed-forward ammonia injection amount dynamic correction look-up table, a speed regulation ammonia injection amount MAP look-up table, a no-load ammonia injection amount MAP look-up table and a smoking limit look-up table are prefabricated in the ammonia fuel engine, supercharging pressure, supercharging temperature and air flow serve as input of the smoking limit look-up table, and cooling water temperature and estimated rotating speed serve as input of the no-load ammonia injection amount MAP look-up table. The pedal position and the estimated rotating speed are used as input in the speed regulation ammonia injection amount MAP look-up table, the estimated rotating speed and the estimated torque are used as input in the feed-forward ammonia injection amount dynamic correction look-up table, and therefore the ammonia injection amount is comprehensively optimized, and the rotating speed of the ammonia engine is controlled. According to the invention, cooperative control of the ammonia fuel engine and the permanent magnet motor can be realized, the use of sensors is reduced, the system control performance is improved, and the method can be applied to mass production.
