No more differentiator in PID

Development of nonlinear lead for precision mechatronics

Industrial PID consists of three elements: Lag (integrator), Lead (Differentiator) and Low Pass Filters (LPF). PID being a linear control method is inherently bounded by the waterbed effect due to which there exists a trade-off between precision tracking, provided by Lag and LPF ...
