This paper discusses an optimization method for the spreading performed by centrifugal spreaders in order to minimize adverse environmental effects owing to application errors. A cost functional relying on a conventional simplified spread pattern model is proposed. In order to take into account the mechanical limits of the device, constraints are introduced. An augmented Lagrangian algorithm is implemented to compute an approximate solution. Numerical experiments show that application errors can be significantly reduced for parallel tracks within a main field body.
