Based on the invariance principle of differential equations a simple, systematic and rigorous adaptive-feedback controller is proposed to stabilize nonlinearly any chaotic systems.

基于微分方程不变性原理，我们提出了一个简单、系统、严格的自适应反馈控制器来非线性地稳定任何混沌系统。

Further more, based on the estimator a high order differential feedback controller is designed, which does not rely on the model of the nonlinear system, and has well stability and robustness.

另外，基于所提出的估计器，本文设计了不依赖非线性系统模型的高阶微分反馈控制器。该控制器稳定性好，鲁棒性强。

A signal (termed the "measured value") which is proportional to the pressure difference is then transmitted by means of a "differential pressure transmitter" to the recorder-controller.

正比于压差的信号（称为测量值）通过“压差变送器”被送至记录控制器。
