Actually, i am working on thermostat. I want to partially switched on the thermostat according to the temperature difference between ambient temperature and room temperature. Please tell me, if you have any related code or model or how can we achieve this ?
Thanks in advance

Hi Danish,
I understand that you are working on a thermostat and would like to control a thermostatic valve to be partially open based on the temperature difference between the ambient and room temperatures. You're seeking guidance on how to model or code this behavior.
Assuming you have the current room temperature and the desired ambient temperature available as variables, you can create a simple proportional control logic in MATLAB where the valve opening is a function of the temperature difference. The valve opening can be scaled between 0 (fully closed) and 1 (fully open) based on the temperature difference.
Here's a simple example code snippet illustrating this concept:
% Define the temperatures (in degrees Celsius)
room_temperature = 20; % Current room temperature
ambient_temperature = 25; % Desired ambient temperature
% Calculate the temperature difference
temperature_difference = ambient_temperature - room_temperature;
% Define the maximum allowed temperature difference
max_temperature_difference = 5; % Maximum difference before the valve is fully open
% Calculate the valve opening as a proportion of the temperature difference
valve_opening = min(max(temperature_difference / max_temperature_difference, 0), 1);
% Apply the valve opening to the thermostat control
% Here you would have your code to control the valve based on the `valve_opening` value
In this example, if the temperature difference is greater than or equal to the `max_temperature_difference`, the valve will be fully open. If the temperature difference is zero or negative, the valve will be closed. For intermediate temperature differences, the valve will be partially open.
If you are interested in creating a more sophisticated control model, consider refering to the documentation of Control System Toolbox" - https://www.mathworks.com/help/control/index.html for tools and functions that can help with designing control systems.
Hope this helps!

Hello Hari, Thank you Hari for reply and sharing the code. The code is related to my query and can be helpful.
However, the problem was already solved by me in the past and implemented. Thank you so much.
