Thus, the current stress and power rating at the secondary-side components are reduced. The current double rectifiers are used at the secondary side to partially cancel the output ripple current. Thus, the sizes of the magnetic components and output filter capacitance are reduced. Due to the resonant behavior by the resonant inductance and resonant capacitance at the transition interval, all switches are turned on at ZVS. The experimental results based on a 1-kW prototype are provided to verify the operation principle of the proposed converter.]]> 60 10 4191 4200 2301 60 10 4201 4214 1278 60 10 4215 4224 1696 $X$-level active neutral point clamped (ANPC) family are based on imbricated and/or stacked switching cells on the one hand, with an additional center tap at the dc bus in three-phase operation on the other hand, several redundancies clearly appear which can be managed to increase the global reliability. For the first time, a general and theoretical methodology used to calculate reliability laws and failure rates and applied to compare two-, three-, and five-level topologies is proposed. Results show that the fault handling of three- and five-level three-phase topologies permits a great increase in reliability over a “relatively” short time duration, in addition to other benefits.]]> 60 10 4225 4233 1248 $(hbox{NTV}^{2})$ modulation method can control the NP voltage balance for any load over the full range of inverter output voltage. However, compared with the nearest-three-vector (NTV) modulation method, $hbox{NTV}^{2}$ increases the switching frequency. This paper combines $hbox{NTV}^{2}$ with NTV, and the two methods are used alternately in a fundamental cycle. The duty-cycle coefficients of the redundant small vectors are analyzed to explore the intervals where NTV can control the NP voltage balance in a fundamental cycle. The proportional parameter, which represents the combination of the two methods in hybrid space vector pulsewidth modulation, can be selected to achieve a high-performance NP balance control and low switching frequency. The steady- and transient-state behaviors of the proposed strategy are analyzed in this paper. The experimental results verify the validity of the proposed strategy.]]> 60 10 4234 4242 1630 60 10 4243 4252 2592 $LC$ filters.

In the proposed system, the inverter has the following two functions: 1) It regulates the velocity of the IPM motor, and 2) it controls the source-side-current waveform. In order to obtain a unity-power-factor operation at the source side, we propose and implement a new control method that regulates the inverter output power. The proposed control method is that the inverter regulates $d{-}q$-axis current synchronous with input voltage. An inverter-output-power controller is positioned between a speed controller and a $q$-axis current controller. The inverter output power is regulated by a proportional–integral and repetitive controller. The maximum power factor obtained by the proposed method is 98.7% at the rated-load conditions. The superior performance of the proposed system is demonstrated by experimental results.]]> 60 10 4427 4437 2710 60 10 4438 4449 2002 60 10 4450 4457 1575 60 10 4458 4467 3226 60 10 4468 4481 2806 60 10 4482 4491 2024 60 10 4492 4499 1027 60 10 4500 4511 2127 60 10 4512 4524 3078 60 10 4525 4535 3210 60 10 4536 4545 1789 60 10 4546 4553 852 60 10 4554 4561 638 60 10 4562 4573 1202 60 10 4574 4589 2239 60 10 4590 4598 2243 60 10 4599 4612 1971 $XY$ micropositioning stage driven by electromagnetic actuators. The stage is constructed with a simple structure by employing double four-bar parallelogram flexures and four noncontact types of electromagnetic actuators to realize the kinematic decoupling and force decoupling, respectively. The kinematics and dynamics modeling of the stage are conducted by resorting to compliance and stiffness analysis based on matrix method, and the parameters are obtained by multiobjective genetic algorithm (GA) optimization method. The analytical models for electromagnetic forces are also established, and both mechanical structure and electromagnetic models are validated by finite-element analysis via ANSYS software. It is found that the system is with hysteresis and nonlinear characteristics when a preliminary open-loop test is conducted; thereafter, a simple PID controller is applied. Therefore, an inverse Preisach model-based feedforward sliding-mode controller is exploited to control the micromanipulator system. Experiments show that the moving range can achieve 1 mm $times$ 1 mm and the resolution can reach $pm 0.4 muhbox{m}$. Moreover, the designed micromanipulator can bear a heavy load because of its optimal mechanical structure.]]> 60 10 4613 4626 1795 60 10 4627 4636 1568 60 10 4637 4649 1602 $n$ poles and $m$ zeros plus unknown time delay $d$; and 3) it allows for accurate investigation of the performance of the control action to exogenous and internal disturbances in the control loop and investigation of different operating points.

The system measurements are collected through a lossy sensor network subject to randomly occurring quantization errors and randomly occurring packet dropouts. The description of deficient statistics of mode transitions that account for known, unknown, and uncertain transition probabilities is comprehensive. A distributed filter design scheme is outlined by explicitly characterizing the filter gains in terms of some matrix inequalities.
