% Study pulse resolution. Demonstrates using a multirate system and dither to reduce the effect of minimum pulsewidths. This script shows the effect of (1) ideal response; (2) minimum pulsewidth, with no other compensation; (3) using a variable pulse period; and (4) the use of dither. The controller is a PD control with no other compensation. The minimum pulsewidth gives a large overshoot since no control is applied until the minimum pulsewidth is exceeded. The dither amplitude needs to be adjusted to get the best response if you change the minimum pulsewidth. Things to try: * Change the number of pulses * Change the magnitude and width of the dither Since version 2. ------------------------------------------------------------------------- See also C2DZOH, CButter, PDDesign, Series, Plot2D, TimeGUI, TriangleWave ------------------------------------------------------------------------- % -------------------------------------------------------------------------- Copyright (c) 1996, 2008, 2015 Princeton Satellite Systems, Inc.
