Abstract

An adaptive sliding mode fault-tolerant controller based on fault observer is proposed for the space robots with joint actuator gain faults. Firstly, dynamic model of underactuated robot deduced combining conservation law linear momentum Lagrange method. Then, manipulator joints obtained by using mathematical operation block matrices, hence measurement angular acceleration base attitude can be ...

An inherent torque ripple characterizes switched reluctance technology from conventional technology. The ultimate aim of this paper is to reduce the motor drive using genetic neural network controller based direct scheme. In proposed appropriate bits data are chosen for training and testing. proper selection learning rate momentum will help in weight adjustment. Here error reduced which proves ...

Sweeping jets are oscillating generated by fluidic oscillators, i.e., devices designed to produce an oscillation of the flow without use any moving parts (Raghu, 2013). A typical configuration such consists expansion chamber connected a high-pressure supply via converging nozzle and provided with feedback channels. The motion in is triggered inherent instability sustained rate across Recently, ...

This paper reports a serial dilution microfluidic network composed of microchannels with a high fluidic-resistance ratio for generating linear concentration profiles as well as logarithmic concentration profiles spanning 3 and 6 orders of magnitude. The microfluidic networks were composed of thin fluidic-resistance microchannels with 160 to 730 microm(2) cross-sectional areas and thick diffusio...
