Does anyone know how to run a SimMechanics robot model iteratively using Matlab code? Specifically, I first established a robot model using SimMechanics. After that, I constructed a neural network based controller using Matlab code, which can output signals to actuate the robot joints. The weights for the neural network are randomly generated. To optimize the weights of the neural network, I employed an evolutionary algorithm. To generate initial populations for the evolutionary algorithm, I used the following pseudo codes.

for 1:popsize

Run Neural Network;

Run SimMechanics Model;

Generate Population Individuals;

end

Can someone tell me how to achieve it? Many thanks!

To run any Simulink model programmatically, you can use the sim command.

The following video is a good introduction to some things you can do. It talks about parallel computing also, but you can ignore it if you want.

Actually, I achieved it by using input the generated data into the SimMechanics model. In the model configuration dialogue, I can set the input data. Thank you for your help.
