倒立摆的模型，通过利用matlab中的simulink仿真模块构造出了一个完整的倒立摆系统(Inverted pendulum model, by using the simulink matlab simulation module to construct a complete system of inverted pendulum)

The article concerns observing states of the Induction Motor (IM) using a Luenberger observer in the speed servo drive. The movement of the motor and observer roots is analyzed for a variable speed. Following the analysis, a new method for gain evaluation of the IM magnetic flux observer is presented. This structure is extended by including an adaptive speed observer. The functionality of the presented method is proved in simulations using MATLAB Simulink.
