磁悬浮转子的非线性控制

Non-Linear Control of Magnetic Suspension Rotors

单轴磁悬浮轴承的模型是非线性最小相位的．其控制可以直接用非线性来控制，与用线性近似的线性控制方法相比较具有反馈精确线性化、高增益反馈等优点．

The control of the magnetic bearing is non-linear minimum phase. The non-linearcontrol method is being introduced into the rotor. As compared with the linear control method of the rotor by linearization approximation, both accurate feedback and high-gainfeedback can be attained in the non-linear control method.
