In this paper, we consider the parallel parking problem of car-like mobile robots. First, a kinematic model of the robot suitable for control applications has been derived. The problem of stabilizing the robot is seen as an extension of the tracking problem. Two types of steering controllers for straight-line tracking: bangbang (optimal) control and saturated control have been proposed. Due to ...

Solid state qubits promise the great advantage of being naturally scalable to large quantum computer architectures, but they also possess the significant disadvantage of being intrinsically exposed to many sources of noise in the macroscopic solid-state environment. With suitably chosen systems such as superconductors, many of sources of noise can be suppressed. However, imprecision in nanofabr...

background and objective: obstructive sleep apnea (osa) is considered a common sleep disorder that increases the risk of traffic accidents among drivers. this study aimed to assess the association between mallampati score and stop-bang (snoring, tiredness, observed apnea, blood pressure, body mass index, age, neck circumference, gender) score in commercial drivers. materials and methods: 1743 m...

Tracking control laws are developed for a rigid spacecraft using both thrusters and momentum wheels. The model studied comprises a rigid body with external thrusters and with rigid axisymmetric wheels controlled by axial torques. Modified Rodrigues parameters (MRPs) are used to describe the kinematics. The thruster torques and the axial motor torques are computed to track given attitude motions...

In a pasteurized milk process, the milk must be heated to above 72C and subsequently cooled to a low temperature about 4C in order to ensure a food safety. According to the real pasteurized milk plant, individually single variable control approach including manual control with butterfly valve and automatic control by on-off controller have been carried out to control milk level at storage tanks...

In order to achieve more flexibility for state feedback control design, a new design method based on Lipschitz switching surfaces is proposed for a class of n-th order linear systems subject to on-off control input in this paper. The Lipschitz switching surface is piecewise smooth and developed by the combination of several available smooth subsurfaces due to the partitioned domains of interest...

The HAUSAT-2 is a 30kg class nanosatellite which is stabilized by 3-axis active control method. Its main mission objectives are to provide studying the scope of activity and ecology of animals using Animal Tracking System (ATS) and collecting the space information data of mission orbit from Electric Plasma Probe (EPP) as a space science payload. 2-axes sun sensors, 3-axes magnetometer, and star...
