These are things you can do easily with Analog Insydes 
(www.analog-insydes.de). 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,
