  • 基于C8051F310的山路转弯预防警示系统

    针对盘山路存在的转弯盲区,即在转弯时司机无法得知弯路对面是否有车辆通过,设计一种基于C8051F310的山路转弯预防警示系统。该系统利用一阶滤波算法检测山路转弯时是否有车辆通过。运用该算法可增强系统检测的实时性,提高检测机动车辆的灵敏度,同时大大减少环境温度对检测的干扰。试验表明该系统能够正确指示出在山路转 ...

  • 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 ...
