Sliding mode (SM) and Proportional-integral-derivative (PID) controller are implemented for Buck converter in a continuous conduction mode. A closed-loop controller system is implemented and goes through the transient time response of buck converter. Sliding mode controller is worked as robust controller and can be used to reduce the Delay time and settling time of the system. In power drives c...

Most of the existing results on distributed distance-based rigid formation control establish asymptotic and often exponentially asymptotic convergence. To further improve the convergence rate, we explain in this paper how to modify existing controllers to obtain finite time stability. For point agents modeled by single integrators, the controllers proposed in this paper drive the whole formatio...

A digitally programmable rail-to-rail CMOS operational amplifier (Op Amp) is designed using standard 0.35 um CMOS process. By using an efficient MOS capacitor is used to compensate the stability of the Op Amp. A compensation current switch is used to adjust the slew rate. Using the schemes, the Op Amp can obtain improved the stability, bandwidth, slew rate and settling time according to the out...

The noise performance of digital correlated double sampling (DCDS) for readout of charge coupled devices (CCD) with dominant white noise is presented. The trade-offs between analogue and digital signal filtering and the impact on the sampling rate are investigated and numerically simulated for realistic systems. The results can be used to select the signal bandwidth, the settling accuracy and t...

Secondary settling tanks (SSTs) are the most hydraulically sensitive unit operations in biological wastewater treatment plants. The maximum permissible inflow to the plant depends on the efficiency of SSTs in separating and thickening the activated sludge. The flow conditions and solids distribution in SSTs can be predicted using computational fluid dynamics (CFD) tools. Despite extensive studi...

In this paper we describe two sensors for measurement of particle size-distribution and settling-velocity distribution. These measurements are critical to the correct estimation of the true sediment concentration in the ®eld, as well as to evaluating models for transport rates of sediments. A multi-angle measurement of laser scattering is made and inverted to obtain the particle size distributi...
