Bettis Hydraulic Actuator

In this model i have used H-bridge mosfets for switching, and an inductor as a filter, R and C as a load(C=90% and R=10% which is a piezo actuator).I have used PWM generator to control the switches, in that i have used internal genration of signals. In every condition the model output should be... Platforms: Matlab

This simple simulation shows the implementation of FbLMS algorithm for a single channel feedback active noise control system. Here, the controller generates an "anti-noise" signal to result a destructive interference at the sensor position. The objective is to minimize the noise residue.FbLMS... Platforms: Matlab

The remarkable advance in hydraulic and electrohydraulic power systems resulted in producing control valves of very short settling time. The rapid closure of hydraulic transmission lines leads to severe pressure surge. The attached Simulink file is developed to evaluate the applicability of... Platforms: Matlab
