Maximum overshoot is defined in Katsuhiko Ogata's Discrete-time control systems as "the maximum peak value of the response curve measured from the desired response of the system. In the "Sine Wave" block, you can give the frequency, amplitude and phase of the signal. In signal processing, control theory, electronics, and mathematics, overshoot is the occurrence of a signal or function exceeding its target. This, of course, only works for very underdamped systems where there are multiple oscillations before the wave is dampened enough to obliterate finding peaks. Custom Linear Fitting Matlab Simulink. Multiplying a sine or cosine function by a constant changes the graph of the parent function; specifically, you change the amplitude of the graph. I have read that the superimposed wave has an amplitude of the sum of the original waves.
