Control of LPV Mechatronic Systems in Presence of Dynamic Uncertainties

This paper introduces a novel method to control linear parameter varying (LPV) systems by employing methodologies and algorithms for deployment of - generally known as - fractional order controllers (FOC). The origin of FOC stems from fractional calculus where arbitrary order dynamic characterising functions can be used as envelop for varying dynamic properties of systems. The main feature employed here is the property of robustness, an intrinsic characteristic of FOC, if tuned accordingly. We present here the rationale and method for injecting a high degree of robustness for LPV dynamic systems. A study case from aerospace engineering is used to illustrate the proposed method and to demonstrate its usefulness. The realistic simulation results indicate that the proposed scheme works well and fulfils the imposed specifications.
