Figure Lengend Snippet: Figure 5. Different block diagrams used for the synthesis of the robust fixed-order H∞ controller.

Article Snippet: It is given by ẋm(t) = ( −2162.7 −47916 0 333.33 0 −128.58 0 2805.4 −72.727 ) · xm(t) + ( 0 −111610 63127 ) · δD(t) (31) where the corresponding transfer function is given by Gn(s) = 53479 × 105 · (s + 145.5) (s + 119.6) · (s2 + 2116 · s + 162.4 × 105) (32) So, it is a nominal model presenting the high static gain Gn(0) = 400.6, from which it is possible to synthesize the robust voltage controller using the PID structure, whose parameters are determined by applying the MATLAB function PidTuner30.
