Electronic module based on system on chip device for hydraulic axis control

Hydraulic axis is a typical mechatronic system that combines fine mechanics, fluid power, electronics and computing. Modern devices embed all their control electronics components into mechanical body for increased reliability, cable reduction or elimination and global miniaturization. This leads to need for small size control electronics, possible only by using system on chip microcontrollers with enough processing power and integrated peripherals. Together with specialists from research Institute for Hydraulics and Pneumatics, our team from Technical University Bucharest started design of an integrated electronic module for hydraulic axis control based on 16-bit system on chip device. Its main features are small size that fits into existing servovalve housing and faster data processing. Extensive testing are performed in laboratory and on test bench to adapt control algorithm to mechanical subsystem specific aspect.
