The equation regarding a circuit is shown in the attached picture. I have the parameters Ci, Cc(t), Vd, and Ri. I want to calculate a(t) in MATLAB, and I have two questions:
How can I calculate it in MATLAB? I tried writing some code, but it failed.
Is there any way to simplify this equation? I mean, is there any estimation or technique that can be used? I have no knowledge regarding the approximation of equations. If there is any tutorial or hint available, it would be greatly appreciated.
Yes, I have the Symbolic Math Toolbox. I also have actual data. Ci and Ri, Vd are constants, while Cc(t) is a time-varying signal. In other words, it is not a known function; it represents a time-varying capacitor that randomly varies over time but I have this signal in MATLAB. Due to this time-varying capacitor, I am currently facing confusion regarding the calculation of a(t) in MATLAB.
