DAE-solvers are used to find the numerical solution of the transient analysis of electrical circuits. For onestep methods, the local truncation error only depends on the last stepsize, but for multistep methods, this error is also depends on previous stepsizes in a nonlinear way. Adaptive stepsize control and order control can be used to control these truncation errors. In connection with the articles of prof.S oderlind, the possibilities of a control-theoretic approach are investigated. For onestep methods, the stepsize control process can be viewed as a digital linear control system for the ...
