Abstract
The paper is concerned with the design of a feedforward control scheme aimed at minimising the waste product from a sinter strand process by manipulating strand speed. The results of simulation exercises are discussed in which the sinter bed is assumed to be composed of a series of lumped sections. The velocity of the flame-front within a section is assumed to be nonlinear and initially proportional to the raw-mix permeability. Permeability data from plant are used as input and strand speed and acceleration are constrained to lie within practically realisable limits. The results of simulation exercises using simple control laws based on straight and weighted averaging of ideal section speeds are presented. The proposed control law involves a technique for modifying the time-shift increments associated with the straight-average law. The reduction obtained in output waste from the strand when the new control law is used is clearly demonstrated
