Abstract

We survey the Proportional-Integral-Derivative (PID) controller variants and we switch them in runtime via reconfiguration, as the control requirements change. Depending on the PID variant, e.g. P, I, PI, PD, PID, PI-PD, the involved computations to produce the control output are different. We rely on a previous published design to shorten the execution cycle of each controller variant, by increasing the number of arithmetic units operating concurrently. Furthermore, we incorporate a design based on multiplexers that allows for eliminating frequent reconfigurations, which were required in the previous work. Finally, we evaluate our approach in terms of resource utilization and reconfiguration time.
