  • Nonlinear and Robust Internal Model Control of a Piezoelectric Actuator Devoted to Characterization at the Micro/Nanoscale
    Proceedings of the American Control Conference, 2018
    Co-Authors: Micky Rakotondrabe, Omar Aljanaideh, Mohammad Aljanaideh
    Abstract:

    In this paper, a nonlinear robust internal model control is suggested to control a piezoelectric actuator that is typified by hysteresis, creep phenomenon and badly damped behavior. The principle of the proposed methodology consists of combining three techniques: i) considering the creep as internal disturbance that can be rejected using a disturbance Observer/Compensator, ii) eliminating of hysteresis with a feedforward Compensator, and iii) handling the dynamics and furnishing the global robustness using a feedback linear internal model controller. The overall nonlinear controller was implemented and verified through hardware-in-the-loop experimental tests to explore its efficiency. The results revealed that hysteresis nonlinearity in excess of 14% was reduced to less than 1%, creep in excess of 22% was completely removed, and finally oscillation with overshoot of 35% was completely damped.

  • Internal-Model-Based Design of Repetitive and Iterative Learning Controllers for Linear Multivariable Systems
    2015
    Co-Authors: Dick De Rooverz, Oh Okko Bosgra, M Maarten Steinbuch
    Abstract:

    Repetitive and iterative learning control are two modern control strategies for tracking systems in which the signals are periodic in nature. This paper discusses repetitive and iterative learning control from an internal model principle point of view. This allows the formulation of existence conditions for multivariable implementations of repetitive and learning control. It is shown that repetitive control can be realized by an implementation of a robust servomechanism controller that uses the appropriate internal model for periodic disturbances. The design of such controllers is discussed. Next it is shown that iterative learning control can be implemented in the format of a disturbance Observer/Compensator. It is shown that the resulting control stucture is dual to the repetitive controller, and that both constitute an implementation of the internal model principle. Consequently, the analysis and design of repetitive and iter-ative learning control can be generalized to the powerful analysis and design proce-dure of the internal model framework, allowing to trade-off the convergence speed for periodic-disturbance cancellation versus other control objectives, such as stochastic disturbance suppression

  • high gain Observer Compensator for rotor resistance variation on induction motor rfoc
    International Conference on Electronics Circuits and Systems, 2007
    Co-Authors: Ahmed Abbou, H Mahmoudi, Abdelhadi Elbacha
    Abstract:

    A robust rotor flux oriented control (RFOC) requires the compensation for the effect of rotor resistance. The variation of rotor resistance due to changes in temperature or frequency degrade the performance of RFOC controller by introducing errors in the estimated flux linkage magnitude, position and the electromagnetic torque. So the compensation for the effect of rotor resistance variation then becomes necessary. This paper investigates the effect of variation of rotor resistance on RFOC performance. A method of rotor resistance estimation using a high-gain Observer has been proposed in this paper.
