چکیده
This paper proposes a novel model-free super-twisting nonlinear sliding mode control (MFSTNLSMC) strategy with an improved smoothing extended state observer (SESO) for permanent magnet synchronous motor (PMSM) drives. First of all, the SESO is introduced to estimate unknown term PMSM ultra-local model. Secondly, surface (NLSMS) designed, which can effectively overcome disadvantages simple and rough signal processing conventional linear surface. At same time, (ST) structure chosen suppress chattering phenomenon improve system robustness. Then, Lyapunov stability theorem used prove proposed algorithm. Finally, both comparative simulations experimental demonstrations verify excellent speed tracking performance robustness strategy.

Sliding Mode Control for Diesel Engine Using Extended State Observer
This paper does a research on turbocharged diesel engines both of air-path or speed-path alone, and proposes a cooperative control strategy of air and speed-path two loop TDE system. For modern diesel engines, accurate air/fuel ratio (AFR) and exhaust gas recirculation (EGR) rates design are very important to meet the requirements of emission standards of NOx and PM. For the EGR and AFR rates a...
متن کاملImproved Optimization Process for Nonlinear Model Predictive Control of PMSM
Model-based predictive control (MPC) is one of the most efficient techniques that is widely used in industrial applications. In such controllers, increasing the prediction horizon results in better selection of the optimal control signal sequence. On the other hand, increasing the prediction horizon increase the computational time of the optimization process which make it impossible to be imple...
