For the simulation of electrical machines and drive systems, the abc-model brings benefits in terms of accuracy, efficiency, and flexibility. In particular, it allows one to naturally include both geometry- and saturation-induced space harmonics. We propose here a novel nonlinear abc-model using current-flux linkage and electromagnetic torque N-dimensional lookup tables (N-D LUTs). The current-flux...
Development and utilization of new energy sources is an important means to reduce environmental pollution and greenhouse gas emissions, including research on solar energy in the realization of large vessels is urgent need to address the issue. Based on the specific parameters of large tankers, based on the PSCAD software to build a photovoltaic power system simulation model and ship power system simulation...
Based on the electromagnetic characteristics of switched reluctance machine (SRM) obtained by finite element method (FEM), two nonlinear mapping relations, namely i(ψ,θ) and T(i,θ), are modeled by BP neural network (BPNN) with Levenberg-Marquardt(LM) algorithm. On this basis, the dynamic simulation model of SRM based aircraft electric brake system (SRM-EBS) is built in Matlab. The performance of SRM-EBS...
Wide-spread use of the model-based design process in automotive powertrain system development is increasing the need for accurate dynamic models. Model-based design inherently requires these models to be rapidly producible and easily verifiable. The High Level Modeling (HLM) approach and corresponding High Level Modeling Tool (HLMT) have been developed in response to these necessities. In this work,...
The steer by wire system offer many benefits compare with conventional steering system. By eliminating the mechanical linkage of column shaft between the steering wheel and the front wheel system, it gives more space efficiency, fuel efficiency in term of functionality and at the same time present challenges to the designer. Many researchers have done their control strategy on steer by wire system...
In case of motors working in complex dynamical regimes, evaluation by modeling and simulation of electromagnetic and mechanical stresses, becomes a mandatory objective. In the present paper, means of investigation are presented and, on this basis, some dynamical processes of traction asynchronous motors are analyzed. The quantitative and qualitative results show an important number of valuable information...
Synchro-self-shifting (SSS) clutch is used widely in the ship propulsion system, power plants and other plants. It is one of the most important parts during the system and needed to be simulated in the simulation research of power plant system. However, the mathematical model of the SSS clutch has almost never been presented in the existing published research reports. It has been shown that the transmission...
The simulation model of high voltage generator is proposed in MATLAB/SIMULINK based on the equivalent mathematical model of the new type generator. Simulation module is established in a single-machine infinite-bus. A high voltage generator prototype rated at 162.5 kVA/5 kV is taken as the research object in this paper. The quasi-synchronizing parallel in operation characteristic is studied with digital...
At the basis of analysis of the mathematical model of the permanent magnet synchronous motor (PMSM) and the principle of field orientated vector control, a novel method for modeling and simulink of PMSM system based on SVPWM is proposed. In Matlab/simulink, the simulation model of the whole system is built, two control loops are used, which are inner current loop and the outer speed loop. By simulating...
This paper presents a simulation method of modularization design for brushless DC motors (BLDCM). Based on the mathematical model of BLDCM, some isolated functional blocks, including BLDCM body block, speed PI controller block, current hysteresis controller block, current reference block, inverter block and commutation logic block, have been modeled in Matlab/Simulink. By the organic combination of...
