Yannier, Selim and Şabanoviç, Asif (2007) Control of piezoelectric actuators using analog sliding mode controller. In: Macha , E and Pawliczek, R, (eds.) Mechatronics Systems and Materials. Opole University of Technology, Opole, Poland, pp. 113-127.
In this work, an analog application for the sliding mode control (SMC) of piezoelectric actuators (PEA) using FPAA is presented. Applied SMC is known to have order of sampling time square tracking error. DSP application of the algorithm suffers from ADC and DAC conversions and faces speed limitations. Moreover PEA is known to have very large bandwidth close to the DSP operation frequency. Therefore, with the direct analog application, improvement of the performance is expected and high frequency operation will be achieved. Experimental results for position tracking using DSP and analog application are presented.
