Popis:	In view of the shape memory alloy (SMA) actuation and sensing properties of smart materials, using of SMA output larger driving force in the process of phase transformation, a biasing SMA rigid elastic coupling drive sucker control system has been designed. Using field programmable gate array (FPGA) for generating a pulse width modulated control mode, the resistance detection feedback circuit controls the current feedback, and monitors the pressure of the adsorption mechanism, thus achieving the micro-adsorption mechanism SMA drive control. Experiments show that the system not only has better precision and a certain response speed, but also has good adaptability and self-protection ability.
