Many control schemes have been proposed for induction motor and permanent magnet synchronous motor control, which are almost highly complex and non-linear. Also, a simple and efficient method for unified control of the electric moto are rarely investigated. In this paper, a novel control method based on rotor flux orientation is proposed. The novelties of proposed method are elimination of q-ax...

This paper presents a low-power FPGA based on mixed synchronous/asynchronous design. The proposed FPGA consists of several sections which consist of logic blocks, and each section can be used as either a synchronous circuit or an asynchronous circuit according to its workload. An asynchronous circuit is power-efficient for a low-workload section since it does not require the clock tree which al...

This report addresses issues related to guaranteeing synchronous message sets with message deadlines equal to periods, in an FDDI network where the timed token protocol is used. FDDI guarantees a bounded access time and an average bandwidth for synchronous traffic, and therefore the timed token protocol is well suited for real-time applications. However, this guarantee alone, though necessary, ...

Recently, various synchronous grammars are proposed for syntax-based machine translation, e.g. synchronous context-free grammar and synchronous tree (sequence) substitution grammar, either purely formal or linguistically motivated. Aiming at combining the strengths of different grammars, we describes a synthetic synchronous grammar (SSG), which tentatively in this paper, integrates a synchronou...

The action systems framework has recently been applied to the area of synchronous VLSI design. Synchronous action systems explicitly model synchronous twophase behavior, making a formal description transparent, in the sense that its hardware implementation can be obtained by a direct mapping. The design methodology is based on correctly transformations of asynchronous circuit descriptions into ...

In this paper, a flexible annotation schema called Structured String-Tree Correspondence (SSTC) is introduced. We propose a variant of SSTC called synchronous SSTC. Synchronous SSTC can be used to describe the correspondence between different languages. We will also describe how synchronous SSTC provides the flexibility to treat some of the non-standard cases, which are problematic to other syn...

Several formalisms have been proposed for modeling trees with discontinuous phrases. Some of these formalisms allow for synchronous rewriting. However, it is unclear whether synchronous rewriting is a necessary feature. This is an important question, since synchronous rewriting greatly increases parsing complexity. We present a characterization of recursive synchronous rewriting in constituent ...

The expression of abnormal microRNA (miRNA, miR) is a ubiquitous feature of colorectal cancer (CRC). The pathological features and clinical behaviors of synchronous CRC have been comprehensively described; however, the expression profile of miRNA and small nucleolar RNA (snoRNA) in synchronous CRC has not been elucidated. In the present study, the expression profile of miRNA and snoRNA in 5 syn...

The inhibitory synapse can induce synchronous behaviors different from the anti-phase synchronous behaviors, which have been reported in recent studies. In the present paper, synchronous behaviors are investigated in the motif model composed of reciprocal inhibitory coupled neurons with endogenous bursting and time delay. When coupling strength is weak, synchronous behavior appears at a single ...

Flux switching permanent magnet synchronous motor (FMSM) has the characteristics such as large output torque, fast speed response and high reliability, so it can be widely used in the field of high-performance and high precision control.In the permanent magnet synchronous motor control system, the speed loop usually adopts the PI control algorithm. Although the PI control algorithm is relativel...
