  • Strong stabilization servo controller with optimization of performance criteria
    Sarjaš, Andrej ; Svečko, Rajko ; Chowdhury, Amor
    Synthesis of a simple robust controller with a pole placement technique and a H. metrics is the method used for control of a servo mechanism with BLDC and BDC electric motors. The method includes ... solving a polynomial equation on the basis of the chosen characteristic polynomial using the Manabe standard polynomial form and parametric solutions. Parametric solutions are introduced directly into the structure of the servo controller. On the basis of the chosen parametric solutions the robustness of a closedloop system is assessed through uncertainty models and assessment of the norm . ... The design procedure and the optimization are performed with a genetic algorithm differential evolution - DE. The DE optimization method determines a suboptimal solution throughout the optimization on the basis of a spectrally square polynomial and Šiljakćs absolute stability test. The stability of the designed controller during the optimization is being checked with Lipatovćs stability condition. Both utilized approaches: Šiljakćs test and Lipatovćs condition, check the robustness and stability characteristics on the basis of the polynomial's coefficients, and are very convenient for automated design of closed-loop control and for application in optimization algorithms such as DE.
