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.

This paper summarizes the Mars Exploration Rover(MER)parachute system,introduces the composition and performance of MER parachute system,and primary work in parachute development,especially includes some detailed problems which have been solved by designers.

The dynamic model of the parachute system with the inverted Y suspension is established,which is widely used in recovery systems.

Simulation models for a spaceship s recovery scenario were presented, which cover the deployment, inflation and full inflation processes of the parachute system and can be used to analyze the whole scenario recovery of spaceship.
