Abstract

This thesis is concerned with hill climbing systems
which may be used for parameter optimisation. A simple
system is described which uses the slope of the cost
function to approach the zero slope condition corresponding
to a unique optimum of a system characteristic.
A theoretical analysis using estimation theory methods
is applied to a range of waveforms to assess their value
in slope estimation in the presence of disturbances and
system irregularities. The principal signals discussed
are two and three level maximal-length sequences and
square waver. Sinc waves are used for comparison
purposes. More complex optimisers using higher order
models of the cost function are also considered with
particular reference to the use of the special properties
of three level maximal-length sequences. The results of
the theoretical studies are confirmed by a series of
experiments using an internal combustion engine test rig
and a description of the preparation of the test rig is
given. Hill climbing was carried out on the ignition
angle to obtain maximum power at full throttle and
trajectories for the hill climbing signals are shown.
