The dual-stator permanent magnet synchronous motor (DSPMSM) features high efficiency and high torque and power density, but its special structure makes it difficult to design and there is no ready-made design software like traditional motors. In this paper, a DSPMSM control system for electric vehicles (EV) is designed, and achieves the field-circuit time-stepping finite element simulation using software...
In the paper a gain-scheduled Linear-Quadratic (LQR) control system for the model of Hybrid Excitation Synchronous Machine (HESM) is presented. A special design feature of the hybrid excitation synchronous machines is an additional control loop which allows to control the resultant magnetic flux. From the control synthesis perspective hybrid excitation synchronous machines can be described as Multi-Input...
This paper reports on the control necessary in a Bristol cylinder sea-wave energy capture device and the issues concerned with harvesting a slow, propagating sea-wave, where the power will pulsate. In the paper a detailed description is put forward for the mechanical system. The control strategies necessary to control a system that is has continuously changing conditions are outlined and simulations...
This paper presents a fuzzy sliding mode controller used for switched reluctance motor speed regulation. Based on the technique of variable structure control (VSC) with sliding mode, we can construct the controller that possesses the merits of both fuzzy controller and variable structure controller. It is called a "fuzzy sliding mode controller" (FSMC). It provides a simple way to solve...
This paper presents a new method of synthesizing a stabilizing control system in current fed inverter driven induction motor (CFIDIM). The method is focused on rotor dynamics and a concept of ``damping torque coefficient (DTC)'' is introduced concerning the electrical torque. At first the control system is synthesized on the assumption that an induction motor is driven by an ideally controllable current...
