<jats:p>A numerical method and a program for the computation of the time responses of any complex multiloop control system are described in principle. The control systems are represented by block diagrams which are formed by the linear and nonlinear blocks well known in control engi neering. The properties of these blocks are given by simple relations between input and output signals in the time domain at discrete and equal intervals. Any number of input signals may be fed into the system at any point of the system. Initial conditions may be treated in a simple way like input signals. The input signals and weighting functions may be arbitrary time functions or impulse func tions given in analytical or numerical form. There is no need for special treatment of algebraic loops and of se quencing. The mathematical method is especially suited for programming an electronic digital computer.</jats:p><jats:p>The simulation program makes the work on the digital computer very easy. It computes the signals as functions of time at all points of the system. Several examples of linear systems were simulated on a Siemens-2002 with favorable results. Among others, a medium-size control system was simulated on this relatively slow computer in 3.2 minutes (compared to a real time of 26 minutes) and with more accuracy than on a medium-size analog com puter.</jats:p>
