I could build the table routh of the characteristic equation of the system by using the function RouthTable( )
I try to find the stability conditions as fonction as the gain g. For that purpose, i have to solve some inequalities.
Each terms of the first column of the routh table should be positive.
I would like to find the conditions on the gain g so that my system is stable.
In order to solve the inequalities as function of g, i must assume the mass, and the spring to be positive. I'm not sure that i have well assumed the parameters to be positive.
Have you some ideas to solve my inequalities and find symbolically the conditions of the gain g?
I attach an extract of my code.
Thank you for your help
