Memristor-based phase-lead controller circuit design

Abstract

Memristor predicted and described by L. O. Chua is a new electrical element. Memristor with variable resistance which changes automatically as its voltage changing can be used as a tunable parameter in control systems. Phase-lead controller is widely used in industrial process control applications. The conventional method for adjusting phase-lead controller parameters is based on the "trial and error" procedure which leads to an inconvenient and approximated design. In the meantime, once the parameters are adjusted, they are fixed during the control system operation. In this paper, memristor-based phase-lead (M-phase-lead) controller is presented. Based on memristor constitutive relations of the memristance and memductance, the proposed M-phase-lead controller is more flexible during the design process. The theoretical description of design scheme is presented and simulation example is given to show the effectiveness of the advocated design methodology. © 2013 Springer-Verlag Berlin Heidelberg.
