this paper continues the authors' former research. It is focused on modelling of an adapting device. The equations used for self-tuning or adaptive systems are adjusted to derive the mathematical model of an adaptronic system and the structural scheme of such system is built based on the scheme of self-tuning system. Adapter is described as open-loop automatic control system with two first-order aperiodic blocks and PI controller. As here the main attention is paid to the adapter and to simplify equations, blocks of the main loops are proportional (P) controllers. This is used to make a simulated computer model for adaptronic system. Adaptronic structures are also often called smart materials or intelligent structures. They can be defined using different paradigms, but two of them prevail. According to the technology paradigm, adaptronic structures are an "integration of sensors, actuators, and controls with a material or structural component". The science paradigm refers adaptronic structures as "material systems that have intelligence and life- like features integrated in microstructure of the material in order to reduce the total mass and energy to produce an adaptive functionality". The adaptronic approach is different from the classical engineering approach. The latter uses mathematical models to calculate the worse conditions that the mechanism or control system can undergo and the algorithm performs the same function and the same energy amount is used at each and every time. The adaptronic approach is inspired by the biological world. So, adaptronic systems work like natural and living systems. Actuators and motors behave like muscles, sensors resemble the "five senses" (hearing, sight, smell, taste and touch). Communication and computational systems (artificial intelligence) correspond to include adaptronic sensors, actuators and artificial intelligence generating impact to change the parameters of controlled object. It will be the focus of the paper and computer simulation of this device is regarded in this paper (3). |
