I'm trying to understand an equation from a motor simulation $\dot w_i (u_ i ,w_i,l _i , \dot l _ i )$
I have a simulated motor and I'm not understanding the math to control it.
This is the equation for the force of the motor, also called an 'actuator'.
$\dot w_i (u_ i ,w_i,l _i , \dot l _ i )$
w ...
