求解n皇后问题的MATLAB源程序。此程序只需输入皇后个数，即可得到所有的解。(N queens problem solving MATLAB source code. Just enter the number of this program at Queen' s, you can get all of the solution.)

该程序利用三阶科斯塔斯环实现锁相环结构，有效的估计输入信号的相位变化，在通信系统的同步上广泛应用。(The program uses the third-order Costas loop to achieve phase-locked loop structure, effectively estimate the phase change of the input signal, widely used in synchronous communications system.)

BUCK电路的双闭环控制matlab仿真，直接能用，参数都设置好了，效果很好。(BUCK circuit double-loop control matlab simulation, can be used directly, parameters are set up, the effect is very good.)

vc调用matlab的例子，亲，使用起来非常方便哦( vc call matlab example, pro, very convenient oh)

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. )
