ABSTRACT
This paper presents automated methodology for synthesizing the design of a mechatronic system using a combination of linear-graph modeling and genetic-program optimization. The linear graph approach is used to model a commercial green-environment liner-less thermal head printer (GE-LTHP), which incorporates both the electrical domain and mechanical domain equations. The Matlab® is used to evaluate the performance of the original and the modified GE-LTHP units. The results show that the main performance attributes of the GE-LTHP such as the printing position, rise time, and settling time are significantly improved by the developed approach.
Keywords: Linear-graphs, Genetic-program optimization, GE-LTHP, Printing position, Settling time.
