Abstract The parameters such as oil density and bulk elastic modulus of hydraulic in steam turbine electro-hydraulic servo system vary with ambient temperature, pressure, other factors, there are unmodeled dynamics the system, so obtaining a satisfactory following effect is challenging task for servo(EHS) system. According to principle force balance flow continuity, mathematical model bilateral...

Autonomous electric vehicles (AEVs) have garnered increasing attention in recent years as they hold significant promise for transforming the transportation sector. However, despite advances field, effective vehicle drive control remains a critical challenge that must be addressed to realize full potential of AEVs. This study presents novel approach AEV concurrently generating suitable speed pro...

Anonymity is important to perpetrators of network-based attacks. One of the simplest ways to remain anonymous is to hide the source of an attack by chaining together multiple connections into an extended connection. This is typically done by logging into a remote host, then from there logging into a third and fourth and so on until, at the final host, an attack is launched. These intermediate h...

We describe the design and testing of a robotic system to assist locomotion training of spinal-injured rodents. The goal of the system is to control and quantify spatialtemporal patterns of movement and forces during the stance and swing phases of rat locomotion. This approach will allow us to provide varying levels of assistance to limb movement during stepping and to quantify the effects of a...

The displacement tracking performance of the electro-hydraulic servo actuator is critical for hydraulic active suspension control. To tackle problem slow time-varying parameters in existing dynamics model, a nonlinear adaptive back-stepping control (ABC) approach adopted. Simultaneously, ABC are difficult to configure, resulting poor effect. An enhanced particle swarm optimization (PSO) integra...

In the rapid changing inter-connected environment, cyber criminals are opting sophisticated tools to hide their identities and locations. Stepping stones are now popular among the miscreants and making the situations worse. The paper details the role of stepping stones in hiding the cyber criminals and highlights it as challenge to differentiate the stepping stones from legitimate computers in ...

This paper presents an attitude control algorithm for a Reusable Launch Vehicle (RLV) with a low lift/drag ratio (L/D < 0.5), in the presence of external disturbances, model uncertainties, control output constraints and the thruster model. The main novelty of proposed control strategy is a new combination of the attitude control methods included backstepping, dynamic inversion and adaptive cont...
