Hybrid Optimization Based FOPI Controller Design with Real-Time Validation

摘要

A hybrid optimization technique has been adopted for the tuning of fractional-order PI controller parameters for satisfying a predefined set of gain and phase margin specifications. The algorithm aims at determining a set of optimal controller parameters by minimizing an objective function framed using the equations defining the margins and corresponding cross-over frequencies. Further, the integrated controlled system has been implemented on a digital signal processor advanced control engineering (dSPACE DS1103) platform and the fractional controller design scheme has been experimentally validated in time and frequency domain for its real-world applicability.
