This paper proposes and studies the phase-shifted chaotic space vector modulation (SVM) scheme for harmonics performance improvement in paralleled voltage-source inverters fed permanent magnet synchronous motor (PMSM) drive. By using the proposed scheme, the current harmonics around the switching frequency and some of its multiples in PMSM are eliminated. Besides, the peaky harmonics around all multiples...
The service choreography gives a global view on the collaboration among a collection of services involving multiple different organizations or independent processes. In this paper, a formal model for service choreography based on WS-CDL language is proposed. This model explores the key concepts related to choreography, such as passing channel, fault handling and finalization mechanisms. This study...
In this paper, a chaotic Pulse width modulation (PWM) closed-loop induction motor drive is proposed and implemented to improve the electromagnetic compatibility (EMC) for electric propulsion. The key is to propose a chaotically amplitude-modulated frequency modulator (CAFM) to modulate the space vector PWM (SVPWM), in such a way that the CAFM-SVPWM scheme is proposed for the vector controlled induction...
Instead of avoiding the occurrence of chaos in motor drives, chaos is positively utilized in this paper. A new chaotic pulse width modulation (PWM) scheme is proposed and implemented for AC motors, which functions to significantly suppress the harmonic peaks and hence the acoustic noise. The key is to employ the Chua's circuit for generation of the desired chaotic sequence. By using a practical induction...
This paper proposes and implements a novel electrically chaotic compactor. A modified time-delay feedback control method is applied to chaoize a DC motor in the compactor. The Poincare map, the bifurcation diagram and the maximum Lyapunov exponent are used to analyze the chaos in the electrically chaotic compactor. Simulation comparison not only proves that the electrically chaotic compactor offers...
