... reference compensating currents can be simply controllability and the robustness under parameters variation expressed as: is ensured by using a hysteresis-band controller. The maximal value of the switching frequency is limited by the i* Fck  i Lak ï€ i Lk, k  A, B ,C (2) proper choice of the coupling ...
372. Induction Machine with Improved Operating Performances for Electric Trucks. A FEM-Based Analysis
Year: 2010, Volume: 10, Issue: 2
... regarding the way mechanism for middle to heavy-duty trucks employed in the traction power is transmitted. The first locomotive with USA where the preoccupation for such solution is static frequency converter comes from 1970 [1]. ascending. Concurrently, the producers have tested different solutions This paper is an initiatory approach, which focuses on the ...

... figure 1. modeling uncertainties, time varying parameter fluctuation, and external disturbances [3, 4]. The main disadvantage of this approach is the high switching frequency of the control action or chattering that VSC system exhibit. Chattering is undesirable since it can excite the unmodeled high frequency dynamics in the non linear system control ...

... the measurement through integration realized in Simulink is given in Fig. 2. Fig. 4 Voltage after the integrator From this simulation, there ensues that for a frequency of the impulses of one impulse per hour in the case of the measurements upon a small concentration of Radon, the method through integration cannot be applied. ...
378. Analysis and Control of a New Dual-input Impedance-based DCÂ…DC Converter for Hybrid PV-FC Systems
Year: 2019, Volume: 19, Number: 4
... [1]. In this topologies, which use a large number of switches and high- regard, the hybrid energy systems (HESs) are installed to frequency transformer (HFT). However, using HFT and a deal with these problems and also provide energy flow and large number of switches increases the converter size ...
