One of the most important aspects is the sampling proces s level In continuous time control systems all the system variable s are continuous signals Whether the system is linear or nonlinear all variables are continu ously present and therefore know Thus the outputs of a digital controller shou ld 64257rst be converted into analog signals before being applied to the systems Another way to lo ok at the problem is that the high frequency components of should be removed before applying to analog If the controller does not include an autotune algorithm or if the autotune algorithm does not provide adequate control for the particular application then the unit must be tuned using trial and error The following is a tuning procedure for the OMEG 1 Standard feedback controller plus RVS Figure 22 Drive circuit board with vibration sensors Rotational Vibration Safeguard RVS Rotational Vibration Safeguard RVS Seeing the future Selected HGST hard drives now have an advanced Rotational Vibration S Bi kh Bh tt ac arya Professor Department of Mechanical Engineering IIT Kanpur Joint Initiative of IITs and IISc Funded by MHRD brPage 2br NPTEL Mechanical Engineering Modeling and Control of Dynamic electroMechanical System Module 4 Lecture 33 Jo 01 01 10 20 15 10 5 02 04 06 08 y brPage 4br EE392m Winter 2003 Control Engineering 44 Example Servosystem command More stepper motor flow through a valve motor torque I control Introduce integrator into control Closedloop dynamics gk gk gk We have no digital cable boxes that will work on digital cable tv No digital cable box is available Digital cable descrambler and digital cable box will be available someday At this time no digital cable tv box is available Look for digital cable de Team 14 .
