Nanopositioning proposes a high demand for its control system. However, hysteresis, a common nonlinear phenomenon existing in piezoelectric actuator, decreases precision of nanopositioning. In this paper, active disturbance rejection control (ADRC) is designed to estimate and cancel the influence of hysteresis, and integral time absolute error (ITAE) optimal index is chosen to determine the parameters...
In this paper, an advanced controller is presented for position tracking control and minimizing control energy of an electro-hydraulic system. An index function is first formulated for the closed-loop performance. The optimal control input is then calculated based on the Taylor series expansion of the index function. For providing information to the control design, mathematical model of the EHS is...
Chest injury during unconstrained frontal collision between human and mobile robot is investigated using computer simulation with MADYMO. To assess the chest injury, Combined Thoracic Index (CTI) and Viscous Criteria(VC) was computed. Computed CTI and VC were converted into AIS level by which injury level was evaluated.
In this paper, an active disturbance rejection control (ADRC) with tracking differentiator (TD) solution is proposed and tested on a certain four operating condition model. The proposed system with a cascaded control scheme is constructed based on a linear Active disturbance rejection controller (LADRC) with parameters optimized under a modified fruit fly algorithm. The tracking performance could...
We performed mathematical modeling population dynamics of phytoplankton in aquatic ecosystems based on interspecific interactions and nutrient pollution and toxic substances. We proposed a method of measuring control multispectral television ecological status of water bodies on the parameters of phytoplankton.
