Yannier, Selim and Şabanoviç, Asif (2007) Analog sliding mode controller for position tracking of piezoelectric actuators. In: 15th Mediterranean Conference on Control and Automation, MED 07, Athens, Greece
In this work, analog application for the sliding mode control (SMC) of piezoelectric actuators is presented. DSP application of the algorithm suffers from ADC and DAC conversions and faces speed limitations. Moreover, piezoelectric actuators are 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. First an appropriate SMC is designed to have continuous control output and then experimental results for position tracking using DSP and analog application are presented for comparison.
