Features and Limitation of the Programmable Analogue Signal Processing for Levitated Devices

This paper presents the current state of art in the control systems applied to levitation control and typical structure of digital control system. A new approach based on programmable analogue devices is proposed and an architecture of the levitation controller is presented. Some advantages and disadvantages of the considered technology are given. Finally the possible application of typical control laws and signal processing are discussed. In the experimen
