A fully differential R-MOSFET-C fourthorder Bessel active lowpass filter employing passive resistors and . cuirent-steering MOS transistors as a variable resistor is proposed. The implementation relies on the tunability of the current-steering MOS transistors operating in triode region which counteract the concert deviation of resistance in integrated circuit manufacturing technology in order t...

Since Taiwan is an endemic area for tuberculosis (TB), differential diagnosis between the intestinal TB and Crohn's disease is an important issue. The steering committee of Taiwan Society of Inflammatory Bowel Disease (TSIBD) has arranged a seminar accordingly on May 24th, 2014 and the different point of views by gastroenterologist, radiologist, pathologist and infectious disease specialist wer...

A computer controlled HMMWV automatically retraces a previously recorded path using navigation data, a process we have termed retrotraverse. A Kalman filter combines the output of two navigation systems, an inertial dead reckoning system and a differential GPS, both with and without carrier phase detection. During retrotraverse, the mobility controller uses a velocity controller and pure pursui...

The paper studies controllability problems for the reachable set of a differential inclusion. These were originally motivated by models of control of a flock of animals. Conditions are derived for the existence or nonexistence of a strategy which confines the reachable set within a given bounded region, at all sufficiently large times. Steering problems and the asymptotic shape of the reachable...

This paper proposes a reconfigurable current steering digital to analog converter (DAC). The differential non-linearity error (DNL) of the DAC is estimated on-chip. This is used to reconfigure the switching sequence to get a lower integral nonlinearity error (INL). A 10 bit segmented DAC along with the associated circuits for DNL estimation was designed and fabricated using 0.35μm CMOS technolo...

This paper investigates robust motion pilot control of a coaxial two-wheeled electric vehicle (CTWEV) where the feedback control system is solely based on the angle of inclination without using any velocity information. H∞ control is employed to design a robust stabilizing controller. The proposed scheme involves an electronic differential steering algorithm to pilot the CTWEV via a joystick. F...

In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

This paper deals with the modelling and control of differential steering for vehicular motions help Sliding Mode Control (SMC) a Super-Twisting Algorithm (STA). A single-track mechanical model dynamics is proposed validated by simulations. strategy based on STA yaw to improve travel comfort stability motion. The desired trajectory given equivalent corrective parts are calculated controller. Sim...

This paper presents a lateral control Advanced Driver Assistance System for cars, which uses both steering and differential braking commands to aid drivers enhance vehicle safety. The proposed strategy LPV PI Observer the estimation of driver performance over range speeds. is then used as scheduling signals activate / deactivate ADAS actuators. tested in simulation with randomly generated profi...
