Using fmincon to optimize Simulink model for optimal trajectory
Hello, so i want to search for optimal trajectory (by defining spline) position input to the Simulink Simscape Multibody model to minimize the total force input to the model. However, I encountered the following error in constraint function.
Error using chckxy
The first and second inputs must be of type double or single.
Error in spline (line 72)
[x,y,sizey,endslopes] = chckxy(x,y);
Error in GetStartedWithProblemBasedOptimizeLiveEditorTaskExample>constraintFcn (line 43)
dataStructure.signals(1).values=spline(nTime,locX,dataStructure.time);
Besides form that, when I try to exclude the constraint, the solution of the optimal trajectory is always the same with the initial points. Can anyone help me with the situation? Hereby I attach the folder.Hello, so i want to search for optimal trajectory (by defining spline) position input to the Simulink Simscape Multibody model to minimize the total force input to the model.
