Thus, by characterizing the inductor at design time and knowing only the inductor current during normal operation, changes in plant gain can be predicted. Now, if the loop gain parameter (KP) can be reduced as inductance falls, the loop dynamics will be maintained. 3. Gain scheduling requires knowledge of the gain in question and a controller with gains that can be modified during operation. This technique is frequently used in robotics, where changing geometries change the apparent inertia in a manner that can be anticipated with accuracy.

It has high frequencies from the steep edges and low frequencies because of the fixed value between edges. Like a Bode plot, step commands excite the system across a broad range of frequencies. In that sense, the step response is an alternative to the frequency response. 7 Questions 1. Evaluate the following transfer functions at 100 Hz.

Sensitive, so adaptive control usually must rely on complex statistical methods such as the Kalman filter. 7 Multiple (Cascaded) Loops Multiple loops are common in control systems. For example, in a motion controller, the innermost loop is a current loop that may reside in a velocity loop, which itself may reside within a position or force loop. 22. When tuning multiloop control systems, follow the procedure developed earlier. The inner loops operate in the next-higher-frequency zone to the outer loop.
