A paper was accepted for IEEE Transactions on Control Systems Technology journal
Recently a paper entitled “Sensor Reduction of Variable Stiffness Actuated Robots Using Moving Horizon Estimation” (Olzhas Adiyatov, Bexultan Rakhim, Altay Zhakatayev, Huseyin Atakan Varol) was accepted for publication on the journal IEEE Transactions on Control Systems Technology.
The main idea of the paper is to use moving horizon estimation (MHE) techniques to estimate the full state of the variable stiffness actuated (VSA) robotic system. This allows to reduce the number of sensors required for the closed loop control of the VSA robot using model predictive control (MPC). Using simulations and real world experiments, it was shown that MHE and MPC based control and estimation framework enables sensor reduction of VSA systems without compromising their performance.
