MATLAB: Close loop

closeregion

I =

     0     0     0     0     0     0   0
     0     1     1     0     1     1   0
     1     0     1     0     1     0   1
     0     1     1     0     1     0   1
     0     0     0     0     1     1   0
     0     0     0     0     0     0   0

I need how many closed regions in the matrix. Here obviously two.Is there any one to help?

B = bwboundaries(I,8,'noholes')

MATLAB: Cannot get the same result in GA as I get in linprog

GA solver is stochastic in nature, there should be no reason to expect the same results as that of linprog. Infact you may not even get the same results for two successive runs of GA.

However there are ways to make the results closer by including a hybrid solver. Change the opts as follows:

opts = gaoptimset('StallGenLimit',500,'Generations',500,'TolFun',1e-1,'HybridFcn',@fmincon);

MATLAB: Close loop PID autotuner

Based on the information you provided, replacing the 'FOC Autotuner' block with a 'Closed-Loop PID Autotuner' block is feasible. The error message you posted indicates possible sample-time mismatch associated with the inserted 'Closed-Loop PID Autotuner' block. To view sample times used in the model, please refer to the following link: https://www.mathworks.com/help/simulink/ug/how-to-view-sample-time-information.html

To resolve the issue, you will need to use 'Rate Transition' blocks to interface blocks with different sample times.Please also note that the 'Current Control' subsystem is a triggered subsystem, which is different from a block with fixed sample time. This triggering settings are because of its synchronization with ADC interrupt (explained in https://www.mathworks.com/help/mcb/ug/prepare-task-scheduling.html). Sample time settings also need to be adjusted accordingly.
