Abstract

This thesis studies height estimation techniques necessary to achieve automatic control of the base cutter height on sugar cane harvesters and, in particular, those techniques analysing the hydraulic oil pressure drop across the base cutter hydraulic motor. Signal processing of pressure information leads to the proposal of pressure variance as a height quantifier. As harvesting conditions are non-stationary, an asymptotically unbiased variance estimator using an exponential data window and possessing adjustable tracking and noise smoothing characteristics is devised, implemented in a real-time microprocessor system and tested.
