TMS28335初始化完成之后， 1、 先DDS产生73.35hz的方波。（问流量管固定频率） 2、 乘法器的另一个数字端输入乘数直接给一个固定值（按照5v），系数是固定的就是对应PID输出的那个接口，串行十二位信号输出（需要先定好一个GPIO接口）。 3、 再延迟一定的时间0.1s或其他时间之后，开始ad采集信号，分别采两路AD信号，此时不稳定（为什么要等到一定的幅值才开始采集AD信号） 4、 选择250点估计一个频率，频率估计的方法采用计算峰值次数的方法或者过零点，总之是为了保证精度采用时域估计的算法，这一块主要是一个扫频子程序，计算频率共振点。 5、 之后改变DDS的输出频率，循环对512点的数据进行扫频的处理 6、 频率控制完成之后，就可以缓慢降低PID控制输出的参数，此时暂时不计算频率，通过不断调整系数使AB的幅度保持在1 的范围内。 7、 测试幅度控制稳定之后a、采用幅度和频率同时控制b。采集数据进入频率估计和相位差估计的后续程序的大循环 8、 注意：采样和控制是同时进行的，所以要设置中断，以及看懂AD的程序，以及内部存储以及数据处理资源的分配。 (TMS28335 initialization is complete, 1, the first DDS generated square wave of 73.35hz. (Q flow tube fixed frequency) 2, another digital side of the multiplier input multiplier directly to a fixed value (in accordance with 5v), the coefficient is fixed corresponding PID output interface, serial twelve signal output (need to be a good one GPIO interface). 3, and then after a certain time delay 0.1s or other time, ad signal acquisition were collected two AD signal instability (Why wait until a certain amplitude began collecting AD signal) 4, 250 point estimate a frequency, frequency estimation method using the method of calculation of the number of peak or zero crossing, in short, in order to ensure the accuracy of time-domain estimation algorithm, this piece is a sweep subroutine to calculate the frequency resonance point. 5, after the change of the output frequency of the DDS data of 512 points, the loop processing Sweep 6, after the completion of the frequency control, it can sl)

uCOS+uCGUI例程，主控芯片为STM32，LCD采用FSMC接口连接，实现图形界面的操作(uCOS+uCGUI routines, the main chip for the STM32, the LCD FSMC interface connector, the operation of the graphical interface)

推挽电路仿真，可以在现在带的参数基础上进行修改，然后就变为自己的了(The push-pull circuit simulation)

定时器：设定时间格式（00：:00）后，到时间弹出提示(timer：set time(00:00),then run up)

说明：  国产ARM芯片，GD32F103系列，替代STM32F103系列，ADC采集项目，编译即可通过，多支持国产芯片。(Domestic ARM chip, gd32f103 series, replace STM32F103 series, ADC acquisition project, compile can pass, most support domestic chips.)

说明：  stm32f103zet6 使用freertos，在IAR平台下开发，静态任务(stm32f103zet6 freertos)

It is well known that the production of hot coils in uniform thickness depends on various process parameters such as the material, the number of rolling stages, the reduction ratio of the thickness, the rolling speed, the front and back tensions, the friction between the material and rolls, the rolling temperature, and the rolling force at each stage of rolling. In the present study, the effect of front and back tensions on reducing the thickness deviations of hot rolled steel strips were investigated by developing a fuzzy control algorithm. In order to derive the fuzzy control rules, rigid±viscoplastic ® nite element simulations were carried out using the material property determined from the production data.
