I found out there is a deadband in my steering controller after several runs. And the transfer function for it in the \$s\$-domain is $$ H(s)=\frac{270\cdot e^{-0.03s}}{0.015\cdot s + 1} $$ To overcome this deadband, should I introduce a compensator ? My control theory background is weak so am not sure of a proper way to manage the deadband.

$\begingroup$ Does the period of delay ever vary with time due to load factors changing? WIth PID feedback, I would increase D gain and consider D^2 or veolicty and acceleration feedback from another sensor or derivative $\endgroup$– Tony Stewart EE75Feb 26, 2019 at 16:51

$\begingroup$ @SunnyskyguyEE75 if i use a lateral controller for a lane keeping system for an example, i can manage this problem by increasing the D-gain in that controller. But im looking for a general solution for the steering controller. $\endgroup$– djackFeb 27, 2019 at 1:54
