... flow and noise signals. In between pulses, the transmitter sees only the noise signal. Therefore, the noise can be continu- ously eliminated after each cycle. This provides a stable zero and eliminates ... runs, and pressure tap and lead line design errors. Under turbulent flow conditions, as much as 10% of the d/p signal can be noise caused by disturbances from valves and...

... problems, increased reliability and improved thermal capacity are achieved. On the other hand, brushless motors require more complex and expensive control systems. Sensors and switching circuitry are ... cheap, robust, and reliable, and at the same time offer good torque characteristics. However, control of such motors is rather complicated. Advanced vector controllers are expen...

... the command and control of a vector such as position or force is not enough to control the interaction between systems (dynamic networks). The controller must also be able to command and control ... measurements, and a controller involving a PD regulator and robust control part. The purpose of the robust controller is to ensure that the control tracking error (i.e., the diff...
