OTA-C Voltage-Mode Proportional- Integral- Derivative (PID) Controller for Dc Motor Speed Control

The paper discusses voltage mode analog circuit implementation of PID controller for speed control of DC motor using Operational Trans conductance Amplifiers (OTAs). OTA-C approach is used to realize the controller due to its features like electronic tunability of its trans conductance and greater bandwidth. The controller parameters are computed in MATLAB using auto-tuning method. The controller with the system is simulated in Cadence environment with AMS 180nm technology. Time domain analysis and the performance of compensated system are presented. Keywords - PID Controller, Speed Control of DC Motor, Operational Trans conductance Amplifier, Tuning Methods
