A fully integrated, reconfigurable step-up DC-DC switched-capacitor power supply solution for energy harvesting system is presented in this paper. A new series-parallel architecture of step-up switched-capacitor converter with Pulse Skip Modulation (PSM) is proposed. This converter generates a stable regulated output (1.2V) from an ultra-low input voltage of 0.3V–1.2V. The designed converter achieves...
The paper presents the dynamic modeling and multi-objective robust Proportional-integral-Derivative (PID) control strategy for a nonlinear process continuous stirred tank reactor (CSTR) system. Motivated by the fact that many existing method involved in design an optimal PID controller based on single performance for the industrial process, multi-objective robust Proportional-integral-Derivative (PID)...
Tropical Cyclone (TC) track prediction is still a big and unsolved problem from the perspectives of theory and application due to the complicated and non-linear physical mechanisms and lack of calculating capabilities and observations. Neural Network works effectively and efficiently in simulating non-linear relationships. Therefore, the present study employs the BP-neural network to predict TC tracks...
A novel equal-status approach synchronization controller design method is presented for improving whole workspace synchronization of flight simulators. The method takes the advantages of transparency for QFT to synthesize equal-status synchronization forward channel controllers, synchronization of which can be evaluated by steady status synchronization conditions. Additionally, feed forward controllers...
A novel quantitative feedback theory (QFT) compound controller design method is presented for improving the whole workspace fidelity of hydraulic flight simulators. The method acquires system models at different operating points of whole workspace through indirect closed-loop identification with power spectrum estimation. Then in controller designing, it designs forward controller and pre-filter with...
