The nonlinear model of a quadrotor

matlab主成分分析的几个案例 包括从协方差矩阵或相关系数矩阵出发求解主成分 从样本观测值矩阵出发求解主成分(Principal component analysis matlab several cases, including the covariance matrix or correlation matrix to solve the main ingredient of departure from the starting sample observation matrix solving the main ingredient)

几个异步电机仿真模型，启动，翻转，调速等(Several induction motor simulation models, starting, turning, speed, etc.)

本文为Stephen J.Chapman《MATLAB 编程（第二版）》英文影印版的中文译本，这本 书对初学者很好的入门教材。(This article Stephen J.Chapman " MATLAB Programming (second edition)," The Chinese translation of the English version of a photocopy, this book is a good primer for beginners.)

说明：  异步电机的精确控制和速度辨识是交流传动系统中重要问题。在该仿真系统中，电机转速采用易于检测的电机定子电压和电流得到转速MRAS辨识算法来估算。由于速度辨识算法中电压模型的纯积分环节会引起的误差积累和漂移问题，采用改进积分型转子磁链估算模型来解决。(The precise control and the speed identification of AC motor are the very important issues on AC drive system.In this system, induction motor is controlled by the direct torque control, stator flux is estimated by u-n model observer that is effective in the full range of speed, motor speed is estimated by MRAS speed identification algorithm that is depended on the voltage and the current of motor stator easily detected. The modified integral rotor flux estimation model is used to solve the problem that the normal model can be affected by the error accumulation and drift of integral calculation in the voltage model of conventional speed identification algorithm. )
