<p>The <em>Environment Panel</em> is designed as a console from which controlling the simulation environment,
particularly the parameters which are not under direct control of the user, so that they cannot be included in the PID control
panel. It also includes tools to perform a comparative analysis of the autotuning
methods in both time and frequency domain.</p>

<p>In the following we will briefly summarize the characteristics of this
interface, which is mainly split in three areas.</p>
<a name="operating_conditions_area"></a><!-- H2 --><a name="t1"></a>
<p><font size=+1 color="#990000"><b>Operating Conditions</b></font><br>
<p>It controls the simulation environment, through the following settings:</p>
<ul>
<li><strong>Measurement Noise</strong>: a check-box menu that allows the insertion
of a measurement noise on the process value with user-defined variance;</li>
<li><strong>Load Disturbance</strong>: a check-box menu that allows the introduction
of a step diturbance on the process value with user-defined amplitude.</li>
</ul>
<a name="operating_conditions_area"></a><!-- H2 --><a name="t2"></a>
<p><font size=+1 color="#990000"><b>Comparative Analysis</b></font><br>
<p>This area include analysis tools for both time and frequency domain. In particular, the time domain analysis perform
a comparison of the responses to a step on the set-point and on the load disturbance for a PID tuned with all the
available methods. The frequency domain analysis, instead, reports the open loop Bode diagram of the control system
together with the Bode diagram of the complementary sensitivity and the sensitivity function.</p>
<p>See a sample of the analisys in the <a href="autopid_exs.html#t2">Example</a> section.</p>
<p><ul><table border=1 cellspacing=0 cellpadding=5 width="90%"><tr>
<td bgcolor="#ffe4b0"><b>Note </b> The comparative analysis is available only when the model is NOT running and
for linear plants. Moreover the name of the blocks inside the Plant subsystem should not be changed since they are used as
references in the functions performing this analysis</a></td>
