Writing text in equation

equationstext;

I can correctly write equation containing text, in latex equation editor online.
So:

\text{Micro-averaged Precision} = \frac{TP_{total}}{TP_{total} + FP_{total}}

Gives:

In Overleaf, this is displayed somehow not as intended (without space):

With the Undefined control sequence. error.

don't ignore errors, you presumably got an error that \text was not defined, load amsmath package. Also use _{\mathrm{total}} don't use math italic for words

use

\begin{equation}\label{eqn: current}
I_{FS} = \sum_{\substack{i}}*\frac{1}{2}*\frac{W}{L}*(V_{gs}-V_{th})^2*(1+\lambdaV_{ds})=\frac{1}{2}*k*(V_{gs}-V_{th})^2*(1+\lambda*V_{ds})*\sum_{\substack{i}}*\frac{W}{L}
\end{equation}

without the $ ...$ They are only for inline math mode, see http://mirror.ctan.org/info/math/voss/mathmode/Mathmode.pdf

I think flalign* and \intertext{} are very good for you.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{flalign*}
& & T_{Loop Filter}(s)&=K_{p}+\frac{K_{i}}{s} & & \\
\intertext{The overall transfer function of given PLL can be given as}
& & \frac{{\phi}_{c}(s)}{{\phi}(s)}&=\frac{T_{Loop Filter}(s)*\frac{1}{s}}{1+\frac{T_{Loop Filter}}(s)*\frac{1}{s}} & & \\
& & \frac{\phi_{c}(s)}{\phi(s)}&=\frac{K_{p}(s)+K_{i}}{s^{2}+K_{p}(s)+K_{i}} & & 
\intertext{In general transfer function for a second order closed loop control system is given as}
& & T_{second order}&=\frac{{\omega}^2+{2{\delta}}{\omega}s}{s_{2}+2{\delta}{\omega}s+{\omega}^{2}} & & \\
& \rlap{\text{On comparing}} & {\omega}&={sqrt{K_i}}  {\delta}=\frac{K_p}{2\sqrt{K_{i}}} & &
\end{flalign*}
\end{document}
