This toolbox allows you to describe electrical and control circuits in the form of netlists, set up the symbolic (differential) equations automatically, and solve them with a DAE solver. Check out the above-mentioned internet site for a free trial version. See the manual for a description of how to solve control circuits. Best regards, Eckhard -- Dr.-Ing.
