The performance optimization control of air propulsion system is a model-based control technology. The system model adopted by each part is one of the key technologies. According to the principle of performance optimization control, the principle of system model selection is analyzed. Described in detail two core models: estimation model and performance optimization model. According to the requirements of real-time control of optimal control, the linearized expression of state variable model and steady-state variable model is given, and the usage of the model in engineering realization is introduced.
