Abstract

This paper presents a performance (Integrated Absolute Error IAE) - robustness (Maximum Sensitivity Ms) tradeoff analysis for First-Order-Plus-Dead-Time (FOPDT) and Second-Order-Plus-Dead-Time (SOPDT) servo-control and regulatory control systems with One-Degree-of-Freedom (1-Dof) and Two-Degree-of Freedom (2-Dof) Proportional Integral (PI) and Proportional Integral Derivative (PID) controllers. Analysis shows that for same model, performance optimized 1-DoF PI controllers are more robust than the PIDs but their optimal performance is lower. The performance optimized regulatory control systems, PI and PID, are less robust than the servocontrol ones, requiring also more performance degradation to reach the same robustness level.
