光伏模型（digsilent）

【实例简介】自己根据论文《汽车自动紧急制动控制策略》所搭建的carsim和simulink联合仿真模型，可以实现不同驾驶工况下的0.4g和0.8g的紧急制动，提供给有需要的朋友

倒车雷达是汽车泊车或者倒车时的安全辅助装置，能以声音或者更为直观的显示告知驾驶员周围障碍物的情况，解除了驾驶员泊车、倒车和起动车辆时前后左右探视所引起的困扰，并帮助驾驶员扫除了视野死角和视线模糊的缺陷，提高驾驶的安全性。本设计利用ATMEL公司的AT89C51单片机、超声波传感器测距实现超声波倒车雷达。利用LED和发光二极管表示传感器探测范围内是否有障碍物，当在探测范围内有障碍物时，发光管以一定频率闪烁，闪烁的频率以距离定，距离越近频率越高。同时蜂鸣器提示报警，探测并指明障碍物距离。

KPCA+SVM源代码，用matlab仿真实现，很实用

stm32使用pwm按键控制led灯强度。此代码用按键控制pwm的占空比改变电压，从而来控制led灯的光亮强度

该程序用最小二乘法实现倾斜校正，校正效果好，程序简单易懂

本资源是作者研究生期间的永磁同步电机入门级仿真，采用旋转高频电压注入，通过高频电流响应来实现转子位置的观测，并采用该方法在DSP实验电机平台上实现。因此，仿真绝对可靠，并且仿真中采用FDAtool实现滤波器功能，可以自由的选择滤波器的截止频率。（因为里面技术含量还有点，上传者也希望通过该资源挣点积分，因此可能比较贵哦）
