Thanks to JLCPCB for supporting this video.
Learn how a PID controller for temperature works. We use a K type thermocouple and read real temperature values with the MAX6675 breakout board. SPI connected to the Arduino which will create the PID and control a MOSFET with PWM signal and the power for a DC heater.

Great explanation! I'm what you could call a beginner in grade 10 at school but I've picked up on the basics really quickly and have decided to do a project for in the house. I am going to use a PID to control the temperature for an espresso machine. This explanation was really useful, but still alot of research to do!

The heating element can be represented by a first-order transfer function if you apply a step input (e.g 5 V or 12 V or whatever the supply voltage is). Plot the transient behaviour as the temperature raises and settles about a value (sample at regular intervals though). This will fit the equation K/(s(tau)+1). K is the gain so that will be the maximum temperature of the plot. Tau is the time constant and this will be the time it takes for the element to reach about 63% of its maximum temperature. You can either simulate this in Simulink and play with the PID values (make sure you use the z-domain rather than the s-domain though. If you don't want to use simulink then just use a tuning method like ziegler nichols

I've been trying to do a PID with Arduino for Sous Vide cooking. The tuning of the PID is the most difficult process for me. The key is to have the patience and good data collection to adjust the various parameters correctly. I tried to doo it with a Crock Pot but there isn't any circulation in a crock pot and I couldn't get the temp deviations down to an acceptable level.. Very good video with good starter information.

@nielslarsen1094 6 жыл бұрын

I like this video. From many years of experience i will advise you to have a function on your coming soldering station controller, where it enters sleep mode, reducing temperature when not being active soldering. This is due to the fact that soldering tips are " burning out ", when standing idle with high temperature. Also the nickel layer is thin, especially on the chinese iron tips you are going to use as per your video.. Kind rgds.

@oscargr_ 6 жыл бұрын

niels larsen. A lot of the burning of tips is due to the fact these soldering irons do *not* have a temperature controller. In order to not be too cold when they are working (touching new cold wire and melting tin) they are getting slightly too much power. Basically, in rest the temperature goes up because nothing cools it down. I agree it is a nice feature to add.

@oscargr_ 6 жыл бұрын

sermad reda. Yes and no. One way to control the temperature of an electric heater is to calculate (or find by trial and error) how much power you need to put in to the heating element to keep it at a constant temperature. At that temperature there is then an equilibrium between the amount of 'heat' you lose (flows from heater to environment) and the amount of heat you add (through electric energy). For every amount of energy you add, the system will end up at a different equilibrium temperature. But this is not very useful, see for example what happens when you blow at the hearter. You remove more heat, and the temperature drops. The advantage of PID is to automatically react to such disturbance by adding more electric power. And you are right, if the P, I, and D you should not see any wobbly output .... Unless your PID actually NEEDS to respond to a disturbance. A PID does not ' *know* '' how much energy it needs, it calculates that based on current, past and expected errors.

Firstly, love the RandM time travel stuff in the background. Secondly, I have completed this tutorial. Everything works wonderfully at 6 Volts; however, when I increase my bench power supply to 12V, the Arduino begins to make a high pitch noise. I'm worried that I may fry the board. Should I perhaps use a 100+ohm resistor between the PWM pin, or am I being stupid? Thanks in advance!!! Ps. This setup has genuinely changed my practical knowledge of PID control!

Hi Electronoobs, Thanks for this excellent tutorial/demo. I have a question though - At 7:46 in your video there are several parts of the wiring that are not in your final schematic. It looks like you've added a diode on the "source" side of the Mosfet (is this connecting source to gate??, but I also see you have a negative (black) jumper looped behind the mosfet - what is that connecting to? I can't see what pin you've connected this to because the mosfet is in the way.

May need elaboration for more advanced engineers on the thermocouple. They DO NOT put out a voltage based on temperature. They work on a difference in temperature between a hot junction and a cold junction. The example video is OK for an elevated temperature in a temperature stable room, but would not work to control the temperature of the room because the cold and hot junctions would be at the same temperature. Great introduction, and a good place for more advanced students to learn about the hot and cold junctions and temperature measurement of the cold junction to get accurate values for the hot junction. The more advanced students and engineers can locate the cold junction in this example.

@bitsurfer0101 2 жыл бұрын

Could you explain how you adjust each parameter? Do you simply adjust the P constant until the desired ramp up speed to temperature is reached for example? Once you have that determined, the D value then becomes the error constant and need to find the happy medium for that (i.e it lands on the right value and doesn't take too long to reach final value)?
