VHDL 基础语法篇
VHDL 基础语法篇 —— VHDL
VHDL硬件描述语言
1.1 VHDL概述
1.1.1 VHDL的特点
VHDL语言作为一种标准的硬件描述语言,具有结构严谨、描述能力强的特点,由于
VHDL语言来源于C、Fortran等计算机高级语言,在VHDL语言中保留了部分高级语言的原
语句,如if语句、子程序和函数等,便于阅读和应用。具体特点如下:
1. 支持从系统级到门级电路的描述,既支持自底向上(bottom-up)的设计也支持从顶向下
(top-down)的设计,同时也支持结构、行为和数据流三种形式的混合描述。
2. VHDL的设计单元的基本组成部分是实体(entity)和结构体(architecture),实体包含设
计系统单元的输入和输出端口信息,结构体描述设计单元的组成和行为,便于各模块之间数
据传送。利用单元(componet)、块(block)、过程(procure)和函数(function)等语句,
用结构化层次化的描述方法,使复杂电路的设计更加简便。采用包的概念,便于标准设计文
档资料的保存和广泛使用。(VHDL Basic Grammar Paper)

MATLAB PV 模块
首先阐述了光伏电池的工作原理及其数学模型,根据数学模型在 MATLAB仿真软件中搭建了光伏电池的工程通用仿真模型。同时,根据生产厂家提供的参数,分析了光伏电池的输出特性曲线,研究了光照强度和环境温度对光伏电池的影响。其次介绍了 MPPT 控制算法的工作原理,比较了 4 种常用控制算法的优缺点,针对单一控制算法无法兼顾跟踪精度和响应速度的问题,分析了基于扰动观察法的模糊控制 MPPT 组合算法并提出了一种新型组合 MPPT 算法,即基于电压自寻优的扰动观察算法。(Firstly, the working principle and mathematical model of photovoltaic cells are described. According to the mathematical model, a general engineering simulation model of photovoltaic cells is built in MATLAB simulation software. At the same time, according to the parameters provided by the manufacturer, the output characteristic curves of photovoltaic cells are analyzed, and the effects of light intensity and ambient temperature on photovoltaic cells are studied. Secondly, the working principle of MPPT control algorithm is introduced, and the advantages and disadvantages of four common control algorithms are compared. Aiming at the problem that single control algorithm can not give consideration to tracking accuracy and response speed, the fuzzy control MPPT combination algorithm based on disturbance observation method is analyzed and a new combined MPPT algorithm, namely voltage-based, is proposed. Self optimizing perturbation observation algorithm.)
