First made UG2 besides to do in the picture compared to front had the very big change, also had the new action in the game pattern, for instance: In interurban strolls, may find photograph (on map by yellow five pointed star expression), here provided the demonstration to love the vehicle the stage, the bonnet, the vehicle door, opened wide them, played the family to be possible in the heartily development vehicle luxury.
前作中 UG2除了在画面上比前作有了很大的改变之外,在游戏模式上也有新的举措,比如:在城市间闲逛的时候,可以找到拍照点(地图上以黄色的五角星表示),这里提供了展示爱车的舞台,引擎盖,车门,敞开他们,玩家可以尽情的展现车内的奢华。

Presents the design of longitudinal control for ASTOVL lift-fan aircraft, a multi-variable, strong-coupling, complicated nonlinear system to make the system nonlinear offset and decouple, and the method used for linear system in designing the system to gain expectant flying qualities and the combination of aerodynamic control surfaces with thrust vectors to delay the control surfaces getting into saturation, and the minimum N-norm generalized inverse theorem of weighted generalized inverse adopted to apportion the moments commands, which make the control surfaces gain appropriate deflection and the simulation results to verify the dynamic inverse control laws designed really make the system nonlinear offset and decouple; when one command is given, only this output will response, and others do not response; when all commands are given together, the responses will be just the linear superpose of the response of each command, therefore the operation of the pilot will be simplified greatly.
摘 要: ASTOVL升力风扇飞机是多变量、强耦合、复杂的非线性系统,采用非线性动态逆理论设计控制律以实现系统的非线性对消及解耦,然后,采用线性系统的设计方法对系统进行设计,以使系统获得期望的飞行品质。同时,考虑到ASTOVL升力风扇飞机是由气动舵面和推力矢量融合作用的,为了延缓各舵面进入饱和的时间,采用加权广义逆中的极小N-范数广义逆定理分配力矩指令,从而使各舵面达到适当的偏转角。并将所设计的控制律进行了仿真,结果验证了所设计的动态逆控制律使系统实现了非线性对消和解耦,单个指令作用时,只有该项响应,其余不受影响;所有指令作用时,其结果就等于单个指令作用时的线性叠加,这样使驾驶员的操纵大大简化而易于控制,从而大大降低了飞行事故率。
