The equations are slightly different and its a difference between time constants and gains.

\$\begingroup\$ How will be both these different in terms of block diagram? \$\endgroup\$– DSP_CSCommented Oct 17, 2019 at 16:41

\$\begingroup\$ They are equivalent, only the constants change. \$\endgroup\$– Voltage Spike ♦Commented Oct 17, 2019 at 18:21

Parallel form means controller will be connected parallel to plant and standard form means controller will be connected in series .

\$\begingroup\$ Please edit your question and add enough information so we can understand what you are asking. Is a plant something that grows in the ground, a manufacturing facility, etc? \$\endgroup\$– GilCommented May 14, 2021 at 2:03
