The amplitude and phase is estimated respectively through a double integrator close-loop, in stead of vector of flux, with angular and speed as feedback.

此方案以估计出的位置角为反馈量，采用闭环双积分结构，分别估计了定子磁链的幅值和相位。

Through adding a power integrator, a partial-state feedback law is constructed to solve the finite-time stabilization problem of the nonlinear systems.

通过利用“加幂积分器”的方法构造出了一个部分状态反馈控制律，解决了这类不确定非线性系统的有限时间镇定问题。
