What is the advantages of port hamiltonian compare with robust, minimax etc?
How to find the differential equation before convert to control system?
such as integrate this y'' + 5*y' + 6*y = 7*u' + 8*u to control system?
How this differential equation relate to the definition of a port hamiltonian system which positive definite, hamiltonian density etc.
is there any tools to integrate this y'' + 5*y' + 6*y = 7*u' + 8*u to control system in Maple?
