WebApr 29, 2024 · We can simply say that the control law is: u = − K x − a x 1 2 + r Where x is a vector of both x 1, x 2 and K is an arbitrary control law matrix and r is the reference vector. Now we have cancel out the nonlinearities for the system due to the − a x 1 2 But then there is something called input-output linearizion. WebNov 18, 2024 · Getty.

WebThe derivative control mode gives a controller additional control action when the error changes consistently. It also makes the loop more stable (up to a point) which allows using a higher controller gain and a faster integral (shorter integral time or higher integral gain).
