Recently, in various fields, research into the path tracking of autonomous vehicles and automated guided has been conducted to improve worker safety, convenience, work efficiency. For systems applied driving technology, it is necessary recognize surrounding environment, determine technology accordingly, develop control methods. Various sensors artificial-intelligence-based perception methods have limitations that they must learn a large amount data. Therefore, particle-filter-based algorithm...
This paper presents a sliding mode control (SMC)-based path-tracking algorithm for autonomous vehicles by considering model-free adaptive feedback actions. In vehicles, safe path tracking requires and robust algorithms because driving environment vehicle conditions vary in real time. this study, the SMC was adopted as method to adjust switching gain, taking into account surface unknown uncertainty make error zero. The can be designed mathematically, but it is difficult express...
This paper presents a sliding mode-based adaptive fault detection and emergency control algorithm for implementation in fail-safe systems of autonomous vehicles. The overall is comprised part part. For the former, mode observer-based algorithms were developed environment chassis sensors, including LiDAR, Radar, acceleration sensors. Unidentified signals from sensors are reconstructed through observer. reconstruction based on MIT rule use an estimated sensitivity parameter. latter,...
Electric vehicles (EVs) use numerous Li-ion battery cells to obtain the pack voltage of hundreds volts and capacities tens kWh. EV management systems (BMSs) monitor control state-of-charge (SOC) state-of-health (SOH) each cell improve energy efficiency address safety concerns while charging discharging. To estimate SOC/SOH from open-circuit-voltage (OCV) a cell, precise measurements (V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CELL</inf> )...
Senescence, a hallmark of aging, is factor in age-related diseases (ARDs). Therefore, targeting senescence widely regarded as practicable method for modulating the effects aging and ARDs. Here, we report identification regorafenib, an inhibitor multiple receptor tyrosine kinases, senescence-attenuating drug. We identified regorafenib by screening FDA-approved drug library. Treatment with at sublethal dose resulted effective attenuation phenotypes βPIX knockdown- doxorubicin-induced...
This paper presents a laser scanner–based predictive safety system for excavators. Blind spots on excavators and operators’ carelessness cause majority of fatal accidents, such as those in which deaths occur due to collisions with objects construction site. A proper can enhance the vehicles sites. In this study, control algorithm collision avoidance was developed utilizing kinematics dynamic model based working area object behavior predictions. The behaviors were predicted by considering...
The study investigates on the optimized steering wheel angle for minimum turning radius of all-terrain crane by applying a model predictive control (MPC) strategy. For this, simplified linear bicycle and error dynamic are firstly derived with multi-axle system. Then, MPC controller is designed an optimal objective function to minimize vehicle radius. corresponding at different speeds analyzed in MATLAB/Simulink environment.
Control delay phenomena, such as time delays and actuator lags, can compromise the control performance of autonomous mobility systems, leading to increased errors. Therefore, it is essential develop a compensation algorithm. This paper proposes Lyapunov-based backstepping steering algorithm compensate for in systems. To estimate system, Recursive Least Squares (RLS) was employed calculate constant real time. The estimated using an RLS designed based on first-order differential equation. A...
