Fuzzy logic controller design for a laser scanner system

The paper describes the design of a fuzzy logic controller (FLC) to meet required performance specifications in a trajectory following problem involving a laser scanner system. The error and the change of error are used as inputs to the FLC, employing a proportional-derivative structure. A detailed analysis of the design factors is included. The fuzzy logic controller was found to be well suited to the system, yielding results that compared favourably to those obtained by various alternative controllers previously developed for the system
