PIC18F8722 PWM电机调节器帮助

问答对人有帮助，内容完整，我也想知道答案 0 大家好，我需要做一个PIC18F822微控制器的项目来控制和调节QuANSER耦合坦克模块。这不是解决家庭作业的要求。好，所以我做了什么，直到现在：我有PICDEM PIC18演示板，我使用电位器作为参考值（设置多少％的坦克将被填充）我使用端口RF1和RF4连接来自坦克1和坦克2I的水平传感器，使用端口RA2 t输出PWM信号在我当前状态下它做什么：读出电位器值并将相同的值设置到PWM你可以选择哪个传感器是活动的（tank1或tank2传感器）如果传感器值低于电位器设置的值，PWM工作在与如果传感器值等于或大于由电位器设置的值，那么PWM被设置为0，电机停止。到目前为止，我所做的是非常低效的，但它尊重我的论文题目，我不想这样，我需要一些提示来做以下工作。基于一些公式，根据期望的水平和值调节发动机的ROT/min。我有一些代码，我知道它可以把数值结果（例如在Volts中——知道我们在这个微控制器上有3.8V）转换为二进制，以实时建立PWM控制。此外，我不会张贴整个源代码，我不想它被那些验证论文的真实性机器人索引，我会张贴部分代码和/或截图。谢谢！以上来自于百度翻译以下为原文 Good day guys, I need to do a project on the PIC18F8722 microcontroller to control and regulate the Quanser Coupled Tanks module. This is not a homework solving request. Good, so what did I do until now: I have the PICDEM PIC18 Demo board and I use the potentiometer as a reference value (to set up how much % the tank will be filled) I use the port RF1 and RF4 to hook up the level sensors from Tank1 and Tank 2 I use the port RA2 to send out the PWM signal What does it do in my current state: Reads out the potentiometer value and sets the same value to the PWM You can select which sensor is active (tank1 or tank2 sensor) If the sensor value is UNDER the value set by the potentiometer the PWM works at the same value readed by the potentiometer If the sensor value is equal or greater than the value set by the potentiometer then PWM is set to 0 and motor stops What I did until now is extremely inefficient - yet it respects my thesis title and I don't want that and I need some tips to do the follwing Somehow I need some live PWM control based on some formula that regulates the rot/min of the engine based on the desired level and value. I have some code that I know it works to convert a numeric result (as in Volts for example - knowing that we have 3.8V on this microcontroller) to binary to set up the PWM control in realtime. Also, I won't post the whole source code, I don't want it to be indexed by those authenticity bots that verify the thesis, I will post part of the code and/or screenshots. Thank you! 0

ADCResult2 is the result received from the sensor where ADCResult is the value that I must set by the potentiometer.

答案对人有帮助，有参考价值 0 你好，罗伯特。是的，你说得对，这正是我第一次尝试解决这个问题。这是我想要的电平（例如60%），这是由传感器读出的电平（当然低于60%），当电平达到60时，PWM被设置为零，如果电平低于预设值，则它返回到100%发动机节气门。但是那并不太好，因为开关可能损坏电机（老师这样建议我，他部分正确），所以我又拍了一张照片。我正在为传感器读取的每个值设置不同的功率设置（例如，0-10%-100%PWM，20-30%-90%PWM……）等等）。我尝试过这个，因为现在我们确信我们的坦克不会溢出，因为停止的命令可能会延迟。好的，现在当我们达到我们期望的水平时，PWM开关到5%以补偿通过井底从水箱流出的水，我将改变或补偿5%到我们实际使用的水量（可能是4%，可能是6%，直到我把它和真实交易联系起来）。这是我的计划，我今晚尝试，并模拟它做我想要的。我不想使用PID（是的，这是我们使用的最佳解决方案，因为我不知道如何实现PID，我不知道如何解释PID，也不知道如何根据变量计算PID）。我试图避免先进的控制解决方案，如P，I，PI，PD，PID的我怎么能！如果你有一个更好的想法如何控制它没有“长期损害”，请让我知道。这是我在模拟中实际工作的演示代码。如果(ADCResult2>==0&安培;ADCResult2&ADCResult2&ADCResult2<=204){CCPR1L=0b01111101;CCPR1L=0b01111101;//100%PWM如果(ADCResult2>ADCResult2>ADCResult2<=306306；//100%PWM如果{CCPR1L=0b01110000；//90%PWM如果(AD如果(ADCResult2>ADCResult2>；=408){CCPR1L=0b00000000110；//5%PWM}}{CCPR1L=0b00000110；//5%PWM}否则{CCPR1L=0b00000000110；//5%PWM}}否则(ADCResult2>_306&__&__;ADCResult2&；ADCResult2<；=408){CCPR1L=0b01100100100100100000000000000100；//80%PWM如果(ADCR结果2>；//80%PWM如果(ADCResult2>；== 408&&ADCResult2<=510){CCPR1L=0b01010111；//70%PWM，如果 (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM }}else if(ADCResult2 >= 510 && ADCResult2 <= 612){CCPR1L=0b01001011; //60%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM }}else if(ADCResult2 >= 612 && ADCResult2 <=714){CCPR1L=0b00111110; //50%PW如果(ADCResult2>==ADCRes.){CCPR1L=0b00000000110；//5%PWM}}如果(ADCResult2>_=714&_&_;ADCResult2&放大器;ADCResult2&>ADCResult2>==ADCResult2>==ADCRes.){CCPR1L=0b000000000000000000000110；//5%PWM}}否则(如果CCPR1L=0b000000000000000000000000000000000000000000000000000000110110110110CCPR1L=CCPR1L=CCPR1L=CCPR1L esult2>=816&ADCResult2<=918){CCPR1L=0b00100101；//如果(ADCResult2>==ADCRes.){CCPR1L=0b00000000110；//5%PWM}}}如果(ADCResult2>__＝918&_____安培;ADCResult2&&&ADCResult2&&00000000000000011001；//20%PWM如果(ADCResult2>ADCResult2>==ADCRCResult2>；=ADCRCRCResultADCResult2>；//20%PWM如果){CCPR1L=0b00000000000000000000000000000000000000000000000ADCResult2>=1020){CCPR1L=0b01111101；//5%PWM}TRISAbits.RA2=0;Bes不要客气，Theo。以上来自于百度翻译以下为原文 Hello Robert. Yes, you are right, exactly that was my first try to solve this problem. Here is the level I want (eg. 60%) here is the level that is read by the sensor (of course under 60%) and when the level reaches 60 the PWM is set to zero, if the level is under the preset value it turns back to 100% engine throttle. But that was not quite ok since on's and off's could damage the motor (I was advised this way by the teacher, and he is partially right) so I took another shot. I am setting a different power setting for each value read by the sensor (eg. for 0-10% - 100% PWM, 20-30% - 90% PWM... etc.). I tried this since now we're sure that our tank will not overflow because the command to stop could come with a delay. Good, now when we reach our desired level the PWM switches to 5% to compensate the water that's going out of the tank through the bottom hole and I'm going to change/compensate that 5% to what we use in reality (maybe 4%, maybe 6%, I can't know that until I hook this up to the real deal). Now that is my plan that I tried tonight and simulated it does what I want. I don't want to use a PID (and yes, that is our best solution to use because I don't know how to implement one, I don't know how to explain one, and I don't know how to calculate one based on my variables). I am trying to avoid advanced control solutions like P, I, PI, PD, PID's how I can! If you have a better idea on how to control it without "long term damage" please let me know. This is my demo code that actually worked in simulation. if (ADCResult2 >= 0 && ADCResult2 <= 204){ CCPR1L=0b01111101; //100%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 204 && ADCResult2 <= 306){ CCPR1L=0b01110000; //90%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 306 && ADCResult2 <=408){ CCPR1L=0b01100100; //80%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 408 && ADCResult2 <= 510){ CCPR1L=0b01010111; //70%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 510 && ADCResult2 <= 612){ CCPR1L=0b01001011; //60%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 612 && ADCResult2 <=714){ CCPR1L=0b00111110; //50%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 714 && ADCResult2 <= 816){ CCPR1L=0b00110010; //40%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 816 && ADCResult2 <= 918){ CCPR1L=0b00100101; //30%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 918 && ADCResult2 <= 1020){ CCPR1L=0b00011001; //20%PWM if (ADCResult2 >= ADCResult){ CCPR1L=0b00000110; //5%PWM } } else if(ADCResult2 >= 1020){ CCPR1L=0b01111101; //5%PWM } TRISAbits.RA2=0; Best regards, Theo.
