I noticed that the "Gain and Phase Margin Plot" block works without any errors on this version of MATLAB. Thus, as a workaround, you can use MATLAB R20
The Gain and Phase Margin Plot and Check Gain and Phase Margins blocks compute a linear system from a nonlinear Simulink® model and display the gain and phase margins during simulation. These blocks are identical except for the default settings on the Bounds tab. The Gain and Phase Margin ...
(s) + − Figure 1: Solution using Matlab For K = 1, the Bode plot is shown in Figure 2. The plot is obtained using the Matlab command margin. From the graph, the phase margin is 3.8658 ◦ , and the gain margin is 0.56057dB. None of these margins is regarded as acceptable (...
Evaluate a MATLAB expression. Stop the simulation and bring that block into focus. During simulation, the block can also output a logical assertion signal. If all bounds are satisfied, the signal is true (1). If any bound is not satisfied, the signal is false (0). ...

W. Bolton, in Instrumentation and Control Systems, 2004 Example Determine the gain margin and the phase margin for a system that gave the following open-loop experimental frequency response data: at frequency 0.005 Hz a gain of 1.00 and phase −120°, at 0.010 Hz a gain of 0.45 and phase...
MATLAB Online에서 열기 Indeed, two phase crossovers are occurring. The first phase crossover is at w = 0 rad/s with Gm = - Inf dB and the second is at w = + Inf rad/s with Gm = + Inf dB. When there are multiple gain and/or phase...
The simulation of the model is performed on MATLAB platform. In this paper, we will discuss in details about the derivation of the model and study of its stability in terms of γ-optimization parameter and phase margin considering both filter configuration in the loop. 展开 ...
