 Let's note $G_t(s)$ the closed-loop transfer function from $w$ to $z$.
 Consider an input sinusoidal signal $w(t) = \sin\left( \omega_0 t \right)$, then the output signal $z(t)$ will be equal to:
 \[ z(t) = A \sin\left( \omega_0 t + \phi \right) \]

 In the previous sections, we have seen that the performances of the system depends on the *shape* of the closed-loop transfer function.
 Therefore, the synthesis problem is to design $K(s)$ such that closed-loop system is stable and such that various closed-loop transfer functions such as $S$, $KS$ and $T$ are shaped as wanted.
 This is clearly not simple as these closed-loop transfer functions does not depend linearly on $K$.

+** Shaping the Sensitivity Function
 <<sec:sensitivity_shaping_example>>
 Let's design a controller using the $\mathcal{H}_\infty$ synthesis that fulfils the following requirements:
 1. Bandwidth of at least 10Hz
 2. Small static errors for step responses
 3. Robustness: Large module margin $\Delta M > 0.5$ ($\Rightarrow \Delta G > 2$ and $\Delta \phi > 29^o$)
- Robustness: Module margin > 2 ($\Rightarrow \text{GM} > 2 \text{ and } \text{PM} > 29^o$)

+
 #+HTML: <details><summary>Hint</summary>
 The typical wanted upper bound of the sensitivity function is shown in Figure [[fig:h-infinity-spec-S-bis]].
 More precisely:
 1. Recall that the closed-loop bandwidth is defined as the frequency $|S(j\omega)|$ first crosses $1/\sqrt{2} = -3dB$ from below
 2. For the small static error, -60dB is usually enough as other factors (measurement noise, disturbances) will anyhow limit the performances
 3. Recall that the module margin is equal to the inverse of the $\mathcal{H}_\infty$ norm of the sensitivity function:
   \[ \Delta M = \frac{1}{\|S\|_\infty} \]
 Remember that the wanted upper bound of the sensitivity function is defined by the *inverse* magnitude of the weight.

 When shaping multiple closed-loop transfer functions, one should be verify careful about the three following points that are further discussed:
 - The shaped closed-loop transfer functions are linked by mathematical relations and cannot be shaped
 - Closed-loop transfer function can only be shaped in certain frequency range.
 - The size of the obtained controller may be very large and not implementable in practice
 #+begin_warning
  Mathematical relations are linking the closed-loop transfer functions.
  For instance, the sensitivity function $S(s)$ and the complementary sensitivity function $T(s)$ as link by the following well known relation:
  \begin{equation}
    S(s) + T(s) = 1
  \end{equation}
  This means that $|S(j\omega)|$ and $|T(j\omega)|$ cannot be made small at the same time!
  It is therefore *not* possible to shape the four closed-loop transfer functions independently.
  The weighting function should be carefully design such as these fundamental relations are not violated.
 #+end_warning
 The control bandwidth is clearly limited by physical constrains such as sampling frequency, electronics bandwidth,
 \begin{align*}
  &|G(j\omega) K(j\omega)| \ll 1 \Longrightarrow |S(j\omega)| = \frac{1}{1 + |G(j\omega)K(j\omega)|} \approx 1 \\
  &|G(j\omega) K(j\omega)| \gg 1 \Longrightarrow |S(j\omega)| = \frac{1}{1 + |G(j\omega)K(j\omega)|} \approx \frac{1}{|G(j\omega)K(j\omega)|}
 \end{align*}
 Similar relationship can be found for $T$, $KS$ and $GS$.
 #+begin_exercice
 Determine the approximate norms of $T$, $KS$ and $GS$ for large loop gains ($|G(j\omega) K(j\omega)| \gg 1$) and small loop gains ($|G(j\omega) K(j\omega)| \ll 1$).
 #+HTML: <details><summary>Hint</summary>
 You can follows this procedure for $T$, $KS$ and $GS$:
 1. Write the closed-loop transfer function $T(s)$ as a function of $K(s)$ and $G(s)$
 2. Take $|K(j\omega)G(j\omega)| \gg 1$ and conclude on $|T(j\omega)|$
 3. Take $|K(j\omega)G(j\omega)| \ll 1$ and conclude on $|T(j\omega)|$
 #+HTML: </details>
 #+HTML: <details><summary>Answer</summary>
 The obtained constrains are shown in Figure [[fig:h-infinity-4-blocs-constrains]].
 #+HTML: </details>
 #+end_exercice
 Depending on the frequency band, the norms of the closed-loop transfer functions depend on the controller $K$ and therefore can be shaped.
 However, in some frequency bands, the norms do not depend on the controller and therefore *cannot* be shaped.
 Therefore the weighting functions should only focus on certainty frequency range depending on the transfer function being shaped.
 These regions are summarized in Figure [[fig:h-infinity-4-blocs-constrains]].

  The order (resp. number of state) of the controller given by the $\mathcal{H}_\infty$ synthesis is equal to the order (resp. number of state) of the weighted generalized plant.
  It is thus equal to the *sum* of the number of state of the non-weighted generalized plant and the number of state of all the weighting functions.
  Two approaches can be used to obtain controllers with reasonable order:
  1. use simple weights (usually first order)
  2. perform a model reduction on the obtained high order controller
