[D08.00015] ROBUST AND OPTIMAL CONTROL FOR SUPERCONDUCTING QUBITS, 2-QUBIT G...HarrisonBall1
Superconducting quantum computers manifest distinct error processes at different levels of system complexity: from leakage or dephasing in individual transmon qubits to errors in two-qubit gates arising from dephasing, imperfect control signals, and unwanted cross-couplings. Quantum control at the physical-layer provides a pathway to combating these errors in today’s quantum hardware. In this talk we describe error modelling of dominant error channels in superconducting circuits relevant for parametrically-activated or cross-resonance gates. Advancing on previous work, we present optimal and robust controls that reduce sensitivity to both leakage and dephasing errors by orders of magnitude, as well as other optimized controls to reduce hardware errors at higher levels of system complexity.
The International Journal of Engineering & Science is aimed at providing a platform for researchers, engineers, scientists, or educators to publish their original research results, to exchange new ideas, to disseminate information in innovative designs, engineering experiences and technological skills. It is also the Journal's objective to promote engineering and technology education. All papers submitted to the Journal will be blind peer-reviewed. Only original articles will be published.
The papers for publication in The International Journal of Engineering& Science are selected through rigorous peer reviews to ensure originality, timeliness, relevance, and readability.
Theoretical work submitted to the Journal should be original in its motivation or modeling structure. Empirical analysis should be based on a theoretical framework and should be capable of replication. It is expected that all materials required for replication (including computer programs and data sets) should be available upon request to the authors.
ENHANCED DATA DRIVEN MODE-FREE ADAPTIVE YAW CONTROL OF UAV HELICOPTERijics
An enhanced data driven model-free adaptive yaw control tracking control scheme is proposed for the yaw
channel of an unmanned-aerial-vehicle (UAV) helicopter which is non-affine in the control input in this paper. Through dynamic linearization and observer techniques, the proposed control algorithm is only based on the pseudo-partial derivative (PPD) parameter estimation derived online from the I/O data of the yaw channel of an UAV helicopter, and Lyapunov-based stability analysis is utilized to prove all signals of
close-loop control system are bounded. Compared with the traditional model free adaptive control
(MFAC), the proposed enhanced MFAC algorithm can make the close-loop control system with stronger robustness and better anti-jamming ability. Finally, simulation results of the UAV yaw channel are offered to demonstrate the effectiveness of the proposed novel control technique.
New Methodology for Asynchronous Motor the Adaptive-Sliding-Mode-Control Capa...TELKOMNIKA JOURNAL
A new methodology for the design of adaptive sliding mode control (ASMC) for Asynchronous motor control will be presented in this paper. The sliding mode control (SMC) has become one of the most active branches of control theory that has found successful applications in a variety of engineering systems, such an the electrical motors. The new Adaptive sliding mode control method is compared to other existing techniques. The pros and cons of ASMC controller will be demonstrated by intensive simulation results. It will be shown that the presented controller is with fast tracking capability, less steady state error, and robust to load disturbance.
