An example of a physically meaningful linear time-variant system?

Following a good tradition of asking for examples of specific systems (non-lin., non-min-phase etc.) I'd like to ask if somebody could give me an example of a simple but still physically...

Is it possible to apply dynamic programming to optimal control problems with fixed right end-point?

In this case, instead of the boundary condition V(Tf) =0 we have V(Tf,xf)=0 which is not enough to solve the related PDE. I wonder if it is possible to extend/modify the classical formulation to...

Can we embed a restriction on the width of pulse in bang-bang optimal control?

I consider a practical optimal control problem with controls entering linearly both the right-hand sides and the cost function. Thus the optimal control must be bang-bang, i.e. a sequence of...

What are the properties of a matrix ODE with symmetric (w.r.t. the origin) eigenvalues?

I consider the following system of matrix ODEs: (*) X'= X*A1 + Y*A2 Y'= -A2^T*X - A1^T*Y, where X, Y, A1, A2 are matrices in R^[nxn], ^T denotes the transpose. So far I know that the...
