A Model for Automatic Control of Vibratory Plate Compactor

Application of automatic control into compaction equipment is one of the most complex problem compared with other machines used in civil engineering works. This is due to the difficulties in getting proper feedback, consisting of a transfer to the compactor and information on the state of soil being just under compaction. The paper presents an approach to this difficulty and practically important problem. The discussion contains evaluation of several different responses of the soil which have been used so far in compaction analysis. Additionally, possibility of applying information on mechanical behavior of compactor without involving mathematical model of soil is considered.
