Active collision avoidance system has received more and attraction, which the capability to avoid potential accidents reduce driver burden. This paper proposes an active consists of a path planner coordinated lateral controller. In planner, cubic B-spline is developed obtain collision-free trajectories bypass obstacle by steering. Based on this, dynamic control autonomous ground vehicles presented improve accuracy robustness following simultaneously ensure vehicle stability via front...

It presents a constrained model predictive control (MPC) scheme to discuss the shared steering with driver. considers from following two aspects that are safety of vehicle and driving intention human. For safety, obstacle avoidance is very important it taken as constraints. Furthermore, vehicle's shape considered. About human, follow driver's command an objective in scheme. Finally, simulations carried out validate effectiveness MPC approach.

A fully synthesizable digital low drop-out regulator (LDO) with dual (coarse/fine) loops control is proposed. This structure employs a synchronized comparator to compare the feedback voltage (Vfb) and desired reference (Vref). coarse loop used simplify logic circuit increase LDO response speed during output dynamic transit. fine minimize ripple of in steady-state. detection using offset comparators employed detect variation. To current consumption, switching frequency scaled 1/32 original...

When a converter is composed of cascaded system with another unknown converter, the optimal design especially important owing to stability systems. Battery `s model introduced analysis. converter's different work conditions are considered. front stage when it discharges, and rear one charges in cascade DC system. From view impedance, it's good for reduce output impedance battery first stage. Another, increasing input could improve becomes one. The equivalent circuit as key component...

Multi-converter power electronics systems are being increasingly used in many applications such as tele-communication systems, international space station, aircraft, electric vehicles, hybrid vehicles and fuel cell vehicles. Tightly regulated converter motor drive tend to behave constant loads(CPL). Stability of the multi-stage intensive loaded by CPLs is a significant design consideration because their potential for negative impedance instability. In order adapt (HEV), this paper stability...
