The experimental study was conducted to investigate the effects of different opening ranges of waste gate of a turbocharged medium displacement spark ignition engine on improving work parameters such as exhaust emission, torque characteristics and fuel consumption. The object of the experimental tests was an engine with modified intake and exhaust manifolds. The intake and exhaust manifold modi...
Electrical on demand supercharging provides an internal combustion engine with the facility to increase its volumetric efficiency without being subject to the mechanical constraints associated with a conventional pressure charging device. This enables improvement in fuel economy through engine downsizing with the added ability to enhance torque. The Visteon Torque Enhancement System (VTES) is a...
in direct torque control, the selection of an applied voltage vector is based on the measuredparameters at the beginning of the sampling period. the delay between the measurement and the application of the voltage vector is the origin of an extra torque ripple. in this paper, a new predictive controller is proposed for compensating this delay and reducing the torque ripple. the stator current i...
The paper proposes a predictive control strategy in discrete time δ-representation in order to reduce the oscillations in the driveline. These oscillations appear in modern diesel engines when a high engine torque is generated at low engine speed. The main object of this paper is to present a model based control concept in δ domain which seems to improve both the control performance and control...
In haptic length perception biases occur that have previously been shown to depend on stimulus orientation and stimulus length. We propose that these biases arise from the muscular torque needed to counteract the gravitational forces acting on the arm. In a model study, we founded this hypothesis by showing that differences in muscular torque can indeed explain the pattern of biases obtained in...
The aim of this paper is to present the difference of induction machine electromechanical characteristics in motor and generator operating modes. Firstly, the paper presents analytically derived equations, which are based on equivalent circuit and are used for calculation of induction machine breakdown torque. Secondly, a comparison of calculated and measured characteristics in motor and genera...
Development of a Clutch Control System for a Hybrid Electric Vehicle with One Motor and Two Clutches
This paper describes a newly developed hybrid electric vehicle system incorporating one motor and two clutches. The mechanical system is connected in a sequence of the engine, the first clutch, the motor, the second clutch and the mechanical gears. The system can transmit driving torque with high efficiency because the friction and pumping loss of the engine are removed by releasing the first c...
A robust control approach is proposed for a high speed manipulator using a hybrid computed torque control approach in the state space. The high-speed manipulator is driven by permanent magnet dc motors to track a trajectory in the joint space in the presence of disturbances. Tracking problem is analyzed in the state space where the completed models are considered for actuators. The proposed con...
