This paper investigates the stabilization of stochastic delayed jumping systems by exploiting a kind of partially delay-dependent controller, where both non-delay and delay states are contained but happen asynchronously. Different from the traditionally stabilizing controller only having non-delay or delay states or containing both, the asynchronous occurring of non-delay and delay terms is modeled...
The ring structure and Boolean variables are investigated and they are used to define the product of Boolean matrices. The logical operators have also been extended to the operators on Boolean matrices. Based on these, the vector distance between Boolean matrices is defined. Some properties are revealed. Finally, the vector distance is used to the analysis of the stability of Boolean networks and...
The concept of canalizing Boolean function is generalized to multi-input multi-output canalizing Boolean mapping. Using the semi-tensor product of matrices and the matrix expression of logical functions, an easily verifiable condition is provided for testing whether a Boolean mapping is a canalizing Boolean mapping. Using it, the disturbance decoupling problem (DDP) of Boolean control networks is...
Networked measurement has become a hotspot in measurement technology. The networked measurement systems based on middleware hold characters such as flexibility, scalability, interoperability, maintainability, reusability and etc, which are the targets pursued by modern measurement systems. In the paper, a platform based on CORBA for open networked measurement system, named NMOP, is detailed. Firstly,...
A control strategy based on single current sensor is proposed for a four-switch three-phase brushless DC (BLDC) motor system to lower cost and improve performance. The system's whole working process is divided into two groups. In modes 2, 3, 5, and 6, where phase c works, phase-c current is sensed to control phases a and b, and phase-c current is consequently regulated. In modes 1 and 4, the combination...
The brushless DC motor has such advantages as simple structure, convenient to control, high reliability, and has been applied in many industrial fields. In order to simplify the converter topology and lower the system cost, four-switch three-phase BLDCM recently becomes research highlight of scholars. Conventional hysteresis controllers suffer from big phase current ripple and inaccuracy current threshold...
