โœฆ Synopsis

A model for the transduction of energy occurring in bacterial #agellar motors is presented. In this model, the in#ux of ions across the channel causes the cyclic conformational change of the channel itself, which in turn produces travelling waves in one of the subcomponents of the motor, the C ring. This wave stabilizes the cyclical movement of the channel which generates the rotating force. The estimated frequency of cyclic conformational change is between 36 kHz and 6.3 MHz, i.e. in the ultrasonic range. This phenomenon is therefore referred to as the ultrasonic micromotor of microorganisms.

Halobacteria are light-sensitive microorganisms which swim by means of rotating flagella. Under constant environmental conditions, they reverse their swimming direction about every 10-30 s. This is due to spontaneous switchings of the flagellar motors from clockwise to counterclockwise rotation or v

## Abstract This paper proposes a PI control method adjusted by a genetic algorithm (GA) for an ultrasonic motor (USM). In the proposed method, proportional and integral gains are adjusted using a GA in order to compensate the characteristic variations of the plant. The effectiveness of the propose
