Computer-aided study of nonlinear systems using an input-output approach

An approach to the computer-aided study of multivariable nonlinear and time-varying systems in the time-domain is outlined, the basis of modern input-output (I/O) theory of control systems. A theoretical justification of the approach is given, together with some observations on the representation problem. The concept of k-time sequence matrices is described. A new simulation language which has been specifically designed to implement this I/O methodology is discussed. An example illustrating one of the I/O representations is presented.<>
