  • Robust tracking system design for a synchronous reluctance motor - SynRM based on a new modified bat optimization algorithm
    Igrec, Dalibor ...
    This paper discusses optimal controller structure design for a Synchronous Reluctance Motor (SynRM). Optimization of controller parameters is based on a new modified BAT optimization algorithm ... (mBAT). SynRM is represented with a nonlinear dynamic model of a synchronous machine. All gathered non-linearities of SynRM are taken into account in the controller's design and optimization procedure withmBAT. A novel SynRM controller structure with a modified robust disturbance observer (mRDO) is pre-sented. The modified mRDO ensures a higher level of stability margin, efficient disturbance rejection, and enables transparent controller parametrization and optimization. Controller synthesis is based onrobust Hpole-placement technique. The Hrobust criteria are presented in the form of spectral poly-nomials and their strong positivity conditions. Spectral polynomials (SP) can be directly used as objectivefunctions in the mBAT optimization procedure. The mBAT algorithm, in terms of the derived SP intro-duces a novel approach to adaptive weighting function selection and modification of BAT velocity in theposition formula. The new modification of the BAT algorithm is inspired by feedback control theory andLyapunov exponential stability property. The proposed modification of the mBAT significantly increasesthe efficiency of the given optimization problem.
