Abstract: This paper presents a novel robust voltage-based control approach for tracking control of electrical manipulators by reducing the effects of uncertainties. The proposed control law is simple, fast response and robust with acceptable tracking error and without chattering problem. This approach is superior to torque-based control approaches due to considering the role of actuators. The ...

This paper presents the modelling of an autonomous amphibious vehicle developed at the Australian Centre for Field Robotics, Sydney. All parts of the vehicle’s driveline from the engine, CVT, gearbox to wheels are analysed and modelled. Results from simulation, compared with data from characterising experiments, show that these models are valid and can be used for the control purpose. Keyword: ...

− This paper describes the development of torque standard machines in China, its measurement range and its measurement uncertainty information etc. Also, the situation of torque standard machines which are in building process or will be built in the future is described in this document. In 1970’s, the first standard machine for measuring torques was developed in Shanghai and it initiated the hi...

Background. One ofthe key components ofpostural control is the motor system's ability to produce appropriate torques to counteract perturbations that may lead to a loss of balance. Evidence exists to show that there is an age-related decline in absolute strength and in the ability to rapidly produce torque. The relationship between age-related decreases in these voluntary torque production capa...

Piston scuffing is one of the destructive faults in internal combustion (IC) engines. There are different causes to make this fault that lack of lubricant is the most important one among them. The purpose of this paper is the quantitative study of the piston scuffing effects on the engine performance parameters which is a new research direction in the IC engine filed. For this reason, several e...

A control oriented engine model is developed to represent a spark ignited engine equipped with a variable cam timing mechanism over a wide range of operating con ditions Based upon laboratory measurements a continuous nonlinear low frequency phenomenological engine model is developed With respect to a xed cam timing engine the VCT mechanism alters the mass air ow into the cylinders the torque r...

Abstract: One objective of this paper is to illuminate fuel economy and emission improvement mechanisms of variable cam timing systems and analyze their effects on engine control system design. By retarding or advancing the cam phase one can vary the engine volumetric efficiency, as well as the amount of exhaust gas that dilutes the air charge. Combining these effects with intake manifold and e...

Modern automotive engines are controlled by the electronic control unit (ECU). The electronically-controlled automotive engine power & torque are significantly affected with effective tune-up of ECU control parameters. Current practice of ECU tune-up relies on the experience of the automotive engineer. The engine tine-up is usually done by trial-and-error method, and then the vehicle engine is ...
