Hello
While SIMULINK does not directly support soft constraints as a default feature, you can achieve this behavior through custom implementation using MATLAB Function blocks and custom scheduling logic. This approach allows you to handle timing overruns and manage the execution of tasks in a way that aligns with the concept of soft constraints.
Here is a basic outline of how you might implement this:
function [nextTimeStep] = customScheduler(currentTime, executionTime)
% Custom Scheduler for Soft Constraints
% Inputs:
% currentTime - The current simulation time
% executionTime - The time taken to execute the current loop
% Output:
% nextTimeStep - The next time step to execute
% Define the fixed time step
fixedTimeStep = 1e-3; % 1ms
% Check if execution exceeded the time step
if executionTime > fixedTimeStep
% Skip the next cycle
nextTimeStep = currentTime + 2 * fixedTimeStep;
else
% Proceed to the next cycle
nextTimeStep = currentTime + fixedTimeStep;
end
end
