AB - In the work problems related to control of precision piezoelectric actuator devices, piezo actuators in particular, are discussed. Multichannel system of control of piezo actuators is presented. Possibility of using the said control system to control the shape of the space-based large transformed antenna is discussed. Keywords- Precision actuator devices, Amplifier driver, Microcontroller, Control signal, Piezo actuator, Stroke length, PCB. 1. Introduction Currently, technical requirements to the precision systems result in the need for search for new technical decisions that would correspond to the requirements at minimum financial expenditures and energy cost though meeting or exceeding its precursors in terms of functionality (Mitin and Krivushov, 2018). One of such decisions is application of high-accuracy positioning piezo actuators operating based on the inverse piezoelectric effect, i.e. on the conversion of electric power into mechanical one (Kuptsov 2016; Vasil’ev et al., 2017; Choe et al., 2017; Vassiliev et al., 2017). Piezo actuators are structures consisting of several piezo elements, which allows enhancing their functional capabilities, improving travel range in particular (Heijer et al., 2014). Figure 1 gives the scheme of one of the possible piezo actuator version consisting of piezo elements multilayer package. Figure 1. Scheme of piezo actuator consisting of
