不受控制

This controller, which is independent of a mathematical model of an induction motor, can accomplish the discrete point-to-point regulation, which is direct and simple to limit the current error within a given tolerance.

这种负载均衡直接控制器不依赖于异步电动机的数学模型，控制效果不受异步电动机的参数影响，它的控制既直接又简化。

Then, three kinds of approaches to simulating the bank erosion process are systematically discussed, which are empirical, extremal hypothesis and mechanical approaches.

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。

The performance of magnetic levitation is determined mainly by the characteristic of its controller and solving the problems of the high precision, high esponse frequency, output immune from the disturbance, the parameter perturbation and the uncertain factors from outside is very difficult. The traditional methods can not meet the needs of the system. So it has great significance to study the control method of magnetic levitation.

磁悬浮系统性能的优劣很大程度上取决于控制器的特性，高精度、高响应频率和输出不受外界干扰的特性以及磁悬浮中参数的摄动和外界不确定的干扰因素都是难以解决的棘手问题，传统控制难以满足系统要求，因此对控制方法的研究有其非常重要的意义。

Because of this Mr. Hall weighs in heavily to document and deplore the strong opposition to using embryonic tissue, mobilized by anti-abortion advocates and conservative politicians who share and support their views, as well as by bioethicists who warn that unchecked biotechnology will ultimately destroy the "natural" human virtues.

因为这一点，霍尔先生引用了大量的文献，并对反对利用胚性组织的强大阻力感到遗憾，这些反对力量是由反堕胎运动者和支持他们意见的保守政治家所组成的，他们也得到那些认为不受控制的生物科技最终将摧毁人类&自然&美德的生物伦理学家的支持。

In contrast to previously characterized human oncogenic retroviruses, the novel retrovirus they had discovered, now known as human immunodeficiency virus, did not induce uncontrolled cell growth.
