Are the optimization results correct ?

Hello everyone
I did a study with the design of experiment with three parameters followed by a GRSM optimization for two objective functions, the simulation are done with 50 iterations the optimization parameters are set by default.
I got a curve of two objective function which does not give the Pareto front. can someone help me ?

    Hi Walid,

     

    The Pareto front is obtained only from DOE studies.

     

    You can choose a solution based on your requirements and what you want the most, for example, to have the highest average toque and the corresponding ripple torque, or the lowest ripple torque and the corresponding average torque. You need to impose your minimum/maximum requirements and the weight(share) of each objective function.

    It's a bit complicated to choose the best solution if you do not impose the weight(share) of each objective function from a multi-objective optimization.

     

    Best regads,

    Alexandru

    thank you Alex I used a constraint now it works very well.

    please, Do you know how to function DOE with optimization GRSM ??
