We consider the problem of shaping transient step response nonlinear systems to satisfy a class integral constraints. Such constraints are inherent in hybrid energy consisting sources and storage elements. While typical specifications aim minimize overshoot, this is unique that it requires presence an appreciable overshoot foregoing The was previously studied context linear paper extends work s...

<p><span>Direct current (DC) motors are widely used in many applications especially those require a speed control, direction and closed-loop control system. In electric vehicle drive system, DC motor is commonly for the propulsion of low power (<250 W) bicycle (e-bike) because it can operate directly from rechargeable batteries with smart controller. driving an e-bike closed ...

This article proposed a novel topology of dynamic voltage regulator using transformer and PWM multi-level AC/AC converter. In this paper for finding the best value of duty ratio for switches to minimize the THD, the GA algorithm has been used and THD output voltage is assumed to be fitness function. The proposed voltage regulator employs multi-level AC/AC converter to generate compensation volt...

The converter valve is the core equipment of DC distribution systems. This paper proposes an autonomous control strategy for grid-connected and islanded operation hybrid topology modular multilevel (MMC). overall structure designed, including outer loop inner current loop. Firstly, loop, it proposed to use equivalent capacitance storage energy MMC power module simulate inertia synchronous gener...

conclusions according to the findings of the current study, both open-loop and closed-loop neuromuscular control mechanisms altered in patients with cai. methods it was a case-control study. twenty-two subjects with unilateral cai and 22 healthy subjects stood on a force plate and initiated gait with maximal velocity under 2 conditions: i) planned (initiated gait after hearing the “all set” sig...

Although LCL filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. Recently, the single-loop control strategy has beensuggested for L or LC filter based grid-connected inverters. However, the use of single-loopcontrol directly in LCL filter-...

In the design of six degrees freedom (6-DOF) flight simulation system, unmodeled dynamic, transient performance and steady-state system are generally concerned. Considering that model is highly nonlinear requires high response speed stability, this paper applies L1 adaptive controller to control platform. The has a low-pass filter in feedback loop avoid frequencies signals, required can be enha...

Inverter voltage control is an important task in the operation of a DC/AC microgrid system. To improve the inverter voltage control dynamics, traditional approaches attempt to measure and feedforward the load current, which, however, needs remote measurement with communications in a microgrid system with distributed loads. In this paper, a load current observer (LCO) based control strategy, whi...

How sensory information influences the dynamics of rhythm generation varies across systems, and general principles for understanding this aspect of motor control are lacking. Determining the origin of respiratory rhythm generation is challenging because the mechanisms in a central circuit considered in isolation may be different from those in the intact organism. We analyze a closed-loop respir...
