This paper presents a novel model-free sliding mode control (MFSMC) method to improve the speed response of permanent magnet synchronous machine (PMSM) drive system. The ultra-local model (ULM) is first derived based on input and output PMSM. Then, MFSMC presented, controller designed ULM MFSMC. A observer (SMO) constructed estimate unknown part ULM. estimated feedbacked perform compensation fo...

Offset-free nonlinear model predictive control (NMPC) can eliminate the tracking offset associated with presence of plant-model mismatch or other persistent disturbances by augmenting plant and employing an observer to estimate both states disturbances. Despite their importance, a systematic approach for generation suitable disturbance models is not available. We propose optimization-based meth...

this paper presents a novel indirect adaptive power system stabilizer (pss) via a developed synergetic control methodology and fuzzy systems. fuzzy system is utilized in an adaptive scheme to estimate the system using a nonlinear model. the synergetic control guarantees robustness of the controller and makes the controller easy to implement because of using a chatter free continuous control law...

in this paper, installment options on the underlying assetwhich evolves according to black-scholes model and pays constant dividendto its owner will be considered. applying arbitrage pricing theory,the non-homogeneous parabolic partial differential equation governingthe value of installment option is derived. then, penalty method is usedto value the european continuous installment call option.
