Poly-optimization: a paradigm in engineering design in mechatronics

Abstract

The paper deals with the Engineering Design that is a general methodology of a design process. It is assumed that a designer has to solve a design task as an inverse problem in an iterative way. After each iteration, a decision should be taken on the information that is called a centre of integration in a systematic design system. For this purpose, poly-optimal solutions may be used. The poly-optimization is presented and contrasted against the Multi Attribute Decision Making, and a set of the poly-optimal solutions is defined. Then Mechatronics is defined and its characteristics given, to prove that mechatronic design process vitally needs CAD tools. Three examples are quoted to demonstrate a key role of the poly-optimization in the mechatronic design.

A sliding mode control strategy for active horizontal seat suspension under realistic input vibration

“…The measured acceleration signals and their power spectral densities are shown in Figure 6. In this paper, the set of optimal control parameters is searched by using the constraint method Tarnowski et al (2011). Such optimisation strategy involves minimising the most important metric of a seat vibro-isolation efficiency min…”

“…In this paper, the set of optimal control parameters is searched by using the constraint method Tarnowski et al (2011). Such optimisation strategy involves minimising the most important metric of a seat vibro-isolation efficiencywhere w 1 and w 2 are the controller settings that are chosen as the decision variables allowing to change the dynamic characteristics of a horizontal suspension system.…”

“…Comsol Multiphysics allowed for the testing of static and dynamic phenomena in electromagnetic fields and simulating displacement of the tested components. Although, the MES calculations can include nonlinearities in determining the parameters of the designed actuator, due to the time-consuming process of the calculations are insufficient for the analysis of extensive control algorithms (Tarnowski and Krzyzynski 2011) or for the self-monitoring system. The best solution seems to be a combination of calculation, where the values determined from FEM models are tabulated and implemented in dynamic models.…”

Dynamic Analysis of the Tubular Linear Actuator With Permanent Magnets

“…The main advantages are the simple design structure, fast response for the input signal, lack of any mechanical transmission from the rotation movement to the linear one [8]. On the other hand there is a not enough mathematical description and algorithms how to design the linear actuator [10]. This is due to the nonlinearity connected with nonlinear distribution of magnetic field in space, current dependency on the coil inductance [1].…”
