The model predictive current control (MPCC) strategy considers all participating voltage vectors to select the optimal voltage vector, which needs comparatively longer computational time to make future current mostly approaching to its reference. In order to decrease time consumption burden, the mathematic model of linear induction machines (LIM) is built up in αβ coordinate instead of dq coordinate...
The simulation of a direct torque hysteresis controller (DTHC) driving an interior permanent magnet synchronous machine (IPMSM) is presented in this paper. The underlying switching concept as well as a proposed experimental setup is discussed. Various simulations, varying the torque and current tolerances, are carried out in the low torque and high torque range. Simulation results show a direct influence...
This paper describes fast analytical model for computation of the switched reluctance machine's (SRM) nonlinear magnetization characteristic and torque lookup table. The flux-tube and the gage-curve methods are used to develop this fast analytical model. Presented model is used for computation of the magnetization characteristic and torque lookup table of three and four-phase SRMs. The simulation...
This paper presents a simulation model of linear switched reluctance motor drives. A Matlab-Simulink environment coupled with finite element analysis is used to perform the simulations. Experimental and simulation results for a double sided linear switched motor drive prototype are reported and compared to verify the simulation model.
This paper proposes a new approach to analyze crosstalk of coupled interconnects in the presence of process variations. The suggested method translates correlated process variations into orthogonal random variables by principle component analysis (PCA). combined with polynomial chaos expression (PCE), the technique utilizes Stochastic Collocation Method (SCM) to analyze the system response of coupled...
A novel methodology for accurate and efficient static timing analysis is presented in this paper. The methodology is based on finding a frequency domain model for the gates which allows uniform treatment of the gates and interconnects. It is shown that despite the highly nonlinear overall gate model, a frequency domain model of the gate with the model parameters, gate moments, as functions of the...
