In this paper, a novel control strategy for the load converter supplying the unbalanced AC load in the renewable energy resources system is presented. This novel control strategy is implemented in the a-b-c coordinate, so reference-frame transformation from a-b-c coordinate to d-q-0 rotating coordinate and inverse transformation from d-q-0 rotating coordinate to a-b-c coordinate are not required which...
Recently, an improved Z-source inverter topology has been proposed to reduce the capacitor voltage stress and limit the inrush current at startup in traditional Z-source inverter. The dynamic modeling and transfer functions are essential to design control schemes for this new topology. This paper presents the small signal modeling and mathematical analysis of the improved Z-source inverter. In particular,...
Positive output Luo converters are a series of DC-DC converters possessing high-voltage transfer gain and small ripple voltage and ripple current. They have very large potential in future industrial applications. Sliding mode control is an effective control method for these converters due to their nonlinear property. Previous work has solved the problem of constant switching frequency. But those controllers...
Measurement concatenation is a general formulation which allows rapidly sampled measurements to be batched and utilized at the slower algorithmic processing rate. It was shown in [Cloutier et al., 1991a] how sequential smoothing and filtering can be carried out within the measurement concatenation structure; a smoothing and filtering algorithm (SFA) was then developed based on a maneuvering target...
The problem of maneuvering target tracking is considered in this paper, with an additional (and non-conventional) target attitude measurement, i.e., fusion of data from a point detection sensor with an imaging sensor. This is motivated by the fact that certain attitude variables such as target orientation can provide faster and more reliable information about target maneuvers or acceleration changes...
The problem of control of discrete-time linear Gaussian systems with Markovian jump parameters is considered in this paper, where both the system state and jump (system mode) can not be observed perfectly. The Dynamic Programming equation is expressed in terms of optimal mode-conditioned cost-to-go and a quadratic control-independent parametrization is used to find a closed form solution for the approximate...
