Hi sir, every time i try to run the simulation i get the error "Error in 'arduino_lab1/Temperature Control Lab/Arduino/Arduino' while evaluating expression." if you could help on this it would be much appriciated sir.
i need a pid controller to control a water valve to control the temp inside of a water tank by increasing or decreasing the water flow using a temperature probe of input. a stepping motor to increase or decrease the water flow . this tank is not connected to a hot water tank it is a separate tank that needs a water vale to increase or decrease temp.
I want to use a set point of 92degreeC in non-linear model but it seems like temp cannot exceed 70dC threshhold. What do I change in the code to remove this limitation.
It is not recommended to remove the safety features. The safety features are that the PWM is set to 200 out of 255. Also, the power supply is 5V that prevents the heater from getting too hot. We've used a 9V power supply for the heaters but then the temperature gets too high. The plastic components start to degrade at about 150 degC.
Is it possible to PID control the trajectory of a differential drive mobile robot operating with an Arduino Microcontroller using Matlab simulink? The mobile robot is comprised of motors connected to pwm pins and there's a camera calculating the error between the desired and the real trajectory .
They are IMC tuning correlations when dead time is zero. You use Kc=1/Kp and KI=Kc/tauP. More information is here: apmonitor.com/pdc/index.php/Main/ProportionalIntegralControl
can someone help me :-( An air-conditioner that you designed previously, has not been performing well for quite some time. The following problems are observed: i. When you set the temperature on the remote to 24°C, the temperature in the room is observed to be ranging between 24±5°C. ii. It takes an extremely long time for the room to cool down and the desired temperature can never be maintained for long. a. The adjustments required to fix the control system and the reasons? b. Name the new controller (P, PI, PD or PID)?
It sounds like the cooling capacity of the air conditioner has decreased. AC units are typically not PID control because the AC is either on or off. It cannot go to 60% of max load. You probably need to clean the condenser or evaporator or check the pressure of the coolant on the suction (low pressure) side.
@@ahmadfathanhalim2636 I hope your project goes well. There is also a Simulink interface here: apmonitor.com/heat.htm that you can use as a template for your project.
+cosmic lion x, you can either build it with a breadboard or you can buy it from apmonitor.com/heat.htm (see button at the bottom).

Yes, I think they check your license credentials as part of the installation. The Python version is also a possibility if you have the TCLab hardware: apmonitor.com/heat.htm
real time ?
Yes, it operates in real-time with the physical hardware. See apmonitor.com/pdc/index.php/Main/ArduinoTemperatureControl for additional details.

How to control the rate of heating?
To explicitly control the rate of heating, use MPC: apmonitor.com/do/index.php/Main/AdvancedTemperatureControl
i need a pid controller to control a water valve to control the temp inside of a water tank by increasing or decreasing the water flow using a temperature probe of input. a stepping motor to increase or decrease the water flow . this tank is not connected to a hot water tank it is a separate tank that needs a water vale to increase or decrease temp.
That sounds like a great application. There is additional information on process control (such as level or temperature) here: apmonitor.com/pdc

How can I read data from the Arduino,
Here is an example with source code: apmonitor.com/pdc/index.php/Main/ArduinoSetup
so basically this is half done? we have to assemble the hardware part on our own and connect it to Matlab ?
The TCLab is available for purchase from Amazon or you can build it: apmonitor.com/heat.htm

As long as you give the trajectory as a setpoint path then it should be able to do that.

Can I know why did u set the proportional = 10

I like from China，thank you.
can someone help me please, what does the blue line in the temperature observer means?
Blue line is the heater level 0 to 💯%
Please, how do I get the system response?ride time...

Hi thank you for this tutorial - are the Simulink/MATLAB files still existing? because I can only find the python files
Yes, the zipped archive has Matlab and Simulink files. See the Download button on apmonitor.com/pdc/index.php/Main/ArduinoTemperatureControl
@@apm the TCLab zip file? It is only containing .py files unfortunately. Thank you for you answer 🙂
@@astronaut205 Thanks for catching that. The Simulink and MATLAB files are restored.
Can gain scheduling apply to this? If so, please teach me.
Yes, check out apmonitor.com/heat.htm for case studies. This TCLab doesn't need grain scheduling but you could practice the methods with it.
is it possible to read data from max6675 module in matlab
I couldn't find anything for Matlab but this may work in Python: github.com/tdack/MAX6675
can i get the simulink file? any clues? the website can't even work
Yes, the files are now available from apmonitor.com/heat.htm from the Download button.
can you do this with a PI controller instead of a PID?
Yes, a PI controller also works. apmonitor.com/pdc/index.php/Main/TCLabPIControl
how to do it if i want to apply FOPDT ?

thank you
Thanks ! Can we use fuzzy-pid controller on plan like this ?
Yes, I think it would also be another type of control for this device.
@@apm okay. Cause its my final project 😁. But i dont now how to connect my plan to simulik 😁
