The invention relates to a dual-rotor engine control method. The method comprises the steps that high-pressure rotor rotating speed, low-pressure rotor rotating speed, a gas compressor outlet total pressure and turbine rear exhaust total temperature serve as the control amounts, through control over the oil supply amount, the control amounts can be adjusted, each control amount is a threshold value, when one control amount is selected as the adjusting amount, the control amounts are monitored in real time, the monitored values and the threshold values are subject to real-time or periodic comparison, and the comparison result serves as the reference for adjusting amount switching. According to an engine adjusting amount optimization mode, through real-time monitoring and adjusting of engineimportant parameters, an engine can be better protected in real time, and the reliable and effective control strategy is provided for safe use of the engine.
