Bettis Hydraulic Actuator

The ThermoFluid library is a free open source physical model library for thermo hydraulic models in the Modelica modeling language.

Although many aspects of a control system can be understood based on linear theory, some nonlinear effects must be accounted for in practically all controllers. Windup is such a phenomena, which is caused by the interaction of integral action and saturations. All actuators have limitations: a...

This simple simulation shows the implementation of FxLMS algorithm for a single channel feed-forward 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.The...

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...

One way to actuate a SimMechanics model is by providing its Actuator blocks with 'Motion' signals. The input to a 'Motion' actuator is a three-element vector containing position, velocity and acceleration signals.In many applications, the only data that is available is the position. This raises...
