| Summary: | 碩士 === 國立中興大學 === 應用數學系 === 88 === The design of simulation proposed in this thesis is a control loading simulation system based on hydraulic actuation. Two axes are set up in the system to simulate the pitch control and the roll control respectively. These axes are connected with a special universal joint at the low end of the control stick. Two sensors are installed for each axes, one is the force cell and the other is the position sensor. The actuator consists of a proportional and directional control valve and a standard hydraulic piston. An 1Hp AC motor and a variable vane pump are used in the hydraulic power unit, while an industrial PC with appropriate input/output cards is used as the controller. The control law is implemented as a software program and is executed within the dedicated PC.
There are two modes for the control loading. One is the “zero-reset” mode and the other is the “zero-hold” mode. In this thesis, we propose a new logic design and a special “zero-hold” control law design. This control logic is simulated using a computer software and is integrated into the mechanical hardware to setup a prototype control loading system. The experimental experiences show that our control design are not only applicable to the control force of rudder pedal or control stick in aircraft simulator and the handler in car drive trainer, but also applicable to the throttle force in aircraft simulator or the gear box force in car drive trainer.
