Based on the data of the parameters recorded by the flight record system in a certain aero - engine and the knowledge of the theory of the propeller system, the paper analyzes and chases up the deviation reasons so as to maintain and recover the performance of the engine.

Static state simulation study of orbital transfer vehicle propulsion system;

Research on modular modeling of marine propulsion system simulation;

Startup process timing analysis of liquid bipropellant pressure-fed propulsion system;

Construction and analysis of nonlinear dynamic model for earth pressure balance type shield hydraulic thrust systems

Synchronization coordinated control of the hydraulic cylinder of the thrust system on shield machines

Mathematical models of PWM,DC permanent-magnet motor,propeller and rudder of thrust system’s component were deduced respectively.

With the fast development of new energy and power electronics, the "green vehicles" have been paid more attention by domestic and international researchers, in which marine electric propulsion systems will be one of the most important applied areas.

For spacecrafts and its propulsion systems, it is very difficult to apply the classical modern control technology to solve the concerned control problems owing to the complexity of systems, the uncertainty and the unknown of the operating circumstances.

The reason of selecting propulsion systems has been analyzed from an investigation on US national programs of Integrated High Performance Turbine Engine Technology, a new concept engine plan of pulse detonation engine, combustion chamber internal flow transition to supersonic ramjet engine.
