Week 5: Added PIDController class to control module and a method to calculate the bandwidth of <code>TransferFunction</code>.
</Title>
<Paragraph className='par'>
This is par
During the fifth week of my Google Summer of Code (GSoC) journey, I introduced significant enhancements to the control module in SymPy. This week’s work included the addition of a new class for PID controllers and a method to compute the bandwidth of transfer functions.
<p>PID Controller:</p>
<Image></Image>
<code>PIDController</code> is a class designed to facilitate the creation and manipulation of PID controllers, which are essential components in control systems. The parameters for the PID controller include:
<ul>
<li><code>kp</code>: Proportional gain (defaults to 0 if not provided).</li>
<li><code>ki</code>: Integral gain (defaults to 0 if not provided).</li>
<li><code>kd</code>: Derivative gain (defaults to 0 if not provided).</li>
<li><code>tf</code>: Derivative filter time constant (defaults to 0 if not provided).</li>
<li><code>var</code>: The complex frequency variable (defaults to <code>s</code> if not provided).</li>
</ul>
<p>Bandwidth Calculation:</p>
A new method, <code>bandwidth</code>, has been added to the <code>TransferFunction</code> class. This method calculates the bandwidth of a given transfer function, providing a valuable tool for analyzing the frequency response of control systems.

Implementation
</Title>
<Paragraph className='par'>
<h2>Enhancements in the Control Module</h2>
<p>The following features were implemented and tested:</p>
<ul>
<li>
<strong>PIDController Class:</strong>
<ul>
<li>Introduced to allow for the creation of PID controllers with customizable parameters.</li>
<li>Supports proportional, integral, and derivative gains, as well as a derivative filter time constant.</li>
</ul>
</li>
<li>
<strong>Bandwidth Calculation:</strong>
<ul>
<li>Added <code>bandwidth</code> method to the <code>TransferFunction</code> class.</li>
<li>Enables the calculation of the bandwidth of transfer functions, aiding in the analysis of control systems.</li>
</ul>
</li>
</ul>
<p>These enhancements are aimed at improving the functionality and analysis capabilities of the control module in SymPy, making it more robust and user-friendly.</p>
