Detailed Description

PID controller with first-order low-pass filtered derivative.

This file defines the control_system::pid::PID_LPF_1 class, which implements a discrete-time proportional-integral-derivative (PID) controller with a first-order low-pass filter applied to the derivative contribution.

The controller uses configurable proportional, integral, and derivative gains, together with a derivative filter cutoff frequency. Previous control errors and controller outputs are maintained as internal state variables.

The controller output is constrained by a configurable maximum output limit.

Template Parameters

T	Numeric data type used for the controller calculations.
