基于EKF的异步电机直接转矩控制系统
为了提高直接转矩控制（DTC）系统定子磁链估计精度，降低电流、电压测量的随机误差，提出了一种基于扩展卡尔曼滤波（EKF）实现异步电机转子位置和速度估计的方法。扩展卡尔曼滤波器是建立在基于旋转坐标系下由定子电流、电压、转子转速和其它电机参量所构成的电机模型上，将定子电流、定子磁链、转速和转子角位置作为状态变量，定子电压为输入变量，定子电流为输出变量，通过对磁链和转速的闭环控制提高定子磁链的估计精度，

基于码本映射的语音带宽扩展算法研究
在现代通信系统中，电话语音的频带被限制在300 Hz～4 kHz的范围内，带来了语音可懂度和自然度的降低。为了在不增加额外成本的前提下提高语音的可懂度和自然度，进行了电话语音频带扩展的研究。提出了一种改进的基于码本映射的语音带宽扩展算法：在码本映射的过程中，使用加权系数来得到映射码本。客观测试结果表明，用此算法得到的宽带语音的谱失真度比用一般的码本映射降低至少2%。主观测试结果表明，用此算法得到的
