چکیده
The wind suddenly blown to the side of car (i.e, cross-wind effect) is considered as one major lateral disturbances, which causes unstable motion vehicle and persistent driving fatigue for driver who tracks desired travel path. In particular, a commercial having large area greatly affected by this effect. Therefore, many related automotive/car manufacturers still wish equip their Advanced Driving Assistant System (ADAS) with crosswind disturbance compensation control system. Meanwhile, in recent advanced systems, rack-type motor-driven power steering (R-MDPS) system more widely used than column-type MDPS (C-MDPS) due structure advantage effective assistance. Recognizing those two issues, paper investigates novel anti-control estimation strategy R-MDPS vehicles non-negligible surfaces. Specifically, an adaptive observer (D.O.B) has been proposed estimate Furthermore, using optimal theory, designed assist possible situations. One when continues steer under effect crosswind, other temporarily loses addition, mode selection conditions between controls are clearly presented maximize efficiency performance Finally, effectiveness evaluated based on Simulink/Carsim Co-simulation HILS environments.

A Novel Control Strategy for a Single-phase Grid-connected Power Injection System
In this paper, a novel and simple control strategy, based on state feedback method is suggested to control the power injection system (PIS). The considered PIS is composed of, a DC voltage source, a voltage source inverter (VSI) and a L-C-L filter. The DC source includes the battery source with boosted voltage. The battery can be charged with photovoltaic cells. Since, the grid voltage acts as ...

متن کاملA model-based PDPC method for control of BDFRG under unbalanced grid voltage condition using power compensation strategy
Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...
