I am getting such error in matlab in BLDC with PWM simulation. What should I do? Can you help me?
Error evaluating 'InitFcn' callback of block_diagram 'BLDC_PWM_control'. Callback string is 'load bldcData'
Caused by: Unable to find file or directory 'bldcData'.

The model (likely) needs information stored in a file called bldcData.mat in order to execute, so the InitFcn callback tries to load the data from that file into the base workspace. Make sure that bldcData.mat is located in a folder on the path. If you don't have bldcData.mat you'll need to get it (except in the unlikely event it's not really needed, in which case you could comment out the load command in the InitFcn). InitFcn doc page
