锁相环的matlab simulink 仿真(The objectives of this laboratory are: To introduce students to Phase Locked Loops (PLL) and their operation. To predict and measure the PLL characteristics. To set up practical circuits using the PLL.)

该文件为matlab工具箱各种代码，供大家使用。(matlab toolbox code)

基于Matlab-Simulink仿真的双闭环直流调速系统的设计与研究 如题,设计要求、设计公式及计算过程比较清晰,格式也是按照标准设置的,正文限于公式编辑的格式,排版不是太完美(Design and Research of Matlab-Simulink simulation of double-loop DC speed control system, such as the title, design requirements, design formulas and calculation process is relatively clear, but also in accordance with the standards set by the format, text format is limited to a formula editing, typesetting is not perfect)

扩散系统之浓度分布的装置。管中储放静止液体B，高度为L=10 ㎝，放置于充满A 气体的 环境中。假设与B 液体接触面之浓度为3 C 0 0.01mol m A = ，且此浓度不随时间改变 而改变，即在操作时间内( h = 10天)维持定值。气体A 在液体B 中之扩散系数为 D m s AB = 2×10− 9 2 。试决定以下两种情况下，气体A溶于液体B中之流通量(flux)。 (a) A 与B 不发生反应； (b) A 与B 发生以下之反应 A+ B→C ， A A − r = kC 其反应速率常数k = 2×10− 7 s− 1。 (Diffusion system of concentration reference device shown in Figure 3. Tube in the store still liquid B, L = 10 cm height, placed in full A gas environment. Assuming the contact surface of the liquid with the B concentration of 3 C 0 0.01mol m A =, and this concentration does not change with time and change, that is, the operating time (h = 10 days) to maintain constant. Gas A in liquid B, the diffusion coefficient D ms AB = 2 × 10-9 2. Decided the following two test cases, the gas dissolved in liquid B in the A liquid (flux). (A) A and B do not react (b) A and B of the following reaction occurs A+ B → C, AA- r = kC, the reaction rate constant k = 2 × 10-7 s-1.)
