The new time-optimal control algorithms presented do not require a-priori knowledge of the process dynamics. They are applicable to systems that can be described by a second-order (or first-order) plus deadtime model and generate a dynamic model as a

Startup control using a novel bang-bang (time-optimal or near-optimal) algorithm that is insensitive to measurement noise, requires little or no tuning, and does not require on unsteady-state model of the process is described. The startup of a batch

A simple algorithm for the time-optimal control of chemical processes during setpoint changes, in processes which can be described by a second-order lag plus dead time model, is described. Knowledge of the unsteady state model parameters is not requi
