Automatic design of robust PID controllers based on QFT specifications
This paper proposes an optimization algorithm for the automatic design of robust PID controllers using Quantitative Feedback Theory (QFT) specifications. The proposed algorithm is based on a criterion to minimize the energy of the control effort. To illustrate the methodology, the pitch angle of a laboratory helicopter is used as a model application with structured uncertainty. The results show...
متن کاملTuning of PID Controllers for First order Stable / Unstable Time Delay Systems with a Zero
PID controllers are designed for First order stable/unstable time delay systems with a zero by using IMC method. In this method first order Pade’s approximation is used while deriving PID controller parameters from IMC controller. Simple tuning rules for stable/ unstable First Order Plus Time Delay (FOPTD) system with a positive zero and unstable FOPTD system with a negative zero are given in t...
متن کاملRobust Gain-Scheduled Smith PID Controllers for Second Order LPV Systems with Time Varying Delay
In this paper, a new approach to design a robust gain scheduled linear parameter varying (LPV) PID controller with pole placement constraints (through LMI regions) is proposed for LPV systems with second order structure and time-varying delay. The controller structure includes a Smith predictor, real time estimated parameters that schedule the controller and Smith predictor (using the known par...
متن کاملOptimal PID-Control on First Order Plus Time Delay Systems & Verification of the SIMC Rules
Optimal PID-settings are found for first-order with delay processes for specified levels of robustness (MS-value) and compared with an extended SIMC-rule. Optimality (performance) is defined in terms of the integrated absolute error (IAE) for combined step changes in load output and input disturbances. The SIMC-rules gives a PI-controller for first order systems and no recommendation are given ...
متن کاملDesign of PID controllers for interval plants with time delay
First of all, the box theorem is extended to the interval plants with the fixed delay. An approach is presented to design the PID controller for interval plants with the fixed delay, which can obtain all of the stabilizing PID controllers. Then, using Hermite–Biehler theorem, extreme point results are provided by the virtual quasi-polynomials. When two virtual and two vertex quasi-polynomials c...
