In this paper, a simple PID controller design method that achieves high performance for wide range of linear self-regulating processes is proposed. Satisfactory responses can be expected with various dynamics, including those low- and high-order, small large dead time, monotonic oscillatory responses. The developed based on second-order plus time modeling technique closed-loop pole allocation strategy through the use root-locus. Simulation examples real-time experiments are given to show...
Abstract In this paper, we consider a class of stochastic functional differential equations with infinite delay at phase space BC ( − ∞ ,0]; R d ) driven by G ‐Brownian motion (SFDEGs) in the framework sublinear expectation spaces . We prove existence and uniqueness solutions to SFDEGs coefficients satisfying linear growth condition classical Lipschitz condition. addition, establish exponential estimate solution.

In a dc microgrid, bidirectional dc–dc converter is an essential link between voltage bus and energy storage system (ESS). When galvanic isolation high efficiency are required, dual active bridge (DAB) preferred. Due to the instability of renewable sources, DAB may transmit or low power ESS. To improve across wide range, this article proposes reactive minimization soft switching optimization algorithm that combines augmented Lagrangian method triple-phase-shift (TPS) modulation. Unlike...
Flexible power point tracking (FPPT) has been presented in the past years to control output of photovoltaic (PV) modules a specific value, which makes PV generation much more friendly system. However, accuracy existing FPPT algorithms is low during fast-changing irradiance. The improved algorithm, consists modified maximum strategy and optimized constant method, proposed. Compared with algorithms, proposed algorithm for systems under various working conditions while energy difference...
A multiport converter with bipolar outputs to integrate renewable energy and storage into the dc bus is desirable solution due its high reliability efficiency. novel symmetric full-bridge four-port based on phase-shift modulated buck–boost voltage balancer proposed in this article. The interleaved bidirectional buck/boost circuit pulsewidth modulation used as primary side achieve integration of storage, whereas derived a secondary generate symmetrical common ground output voltage....
In this paper, a new method for process frequency response identification is proposed, which can identify multiple points on from single relay feedback test. The output and input responses to the test are decomposed into transient parts stationary cycle parts. These then transformed their using DFT digital integration, respectively, obtain response. Real-time tests of various processes give quite accurate responses, especially in important range zero critical frequency. testing conditions...
A current sensor based global maximum power point tracking (GMPPT) algorithm of photovoltaic system is proposed in this article to increase the speed during partial shading condition. For algorithm, range duty cycle reduced by calculating both upper limit and lower skipping section without point. Compared with trapezium (MPT) combination MPT search-skip-judge, reduces directions only needs one realize control. As a result, shows advantages fast speed, small energy loss, low hardware cost....
Global flexible power point tracking (GFPPT) is proposed to realize the (FPPT) of photovoltaic systems under partial shading conditions (PSC). Because working process GFPPT similar global (GMPPT), performance can be improved by applying existing advanced GMPPT algorithm. However, improvement limited while algorithm directly. So, a target-voltage-iterations (TVI) based in this article further increase during PSC. Compared with algorithms, TVI-based shows advantages fast-tracking speed and...
Internal model control (IMC) is a well-known and effective scheme. However, when unstable processes are concerned, the original IMC structure cannot be directly used for system implementation. In this paper, new scheme called partial internal (PIMC) proposed, which capable of controlling both stable processes. PIMC, process expressed as sum antistable parts only part model. The canceled by remaining stabilized controlled with primary controller, usually PID-type regulator low order. Various...
