| 1 | Genetic algorithm tuned PI controller on PMSM simplified vector control显示文摘A simple control structure in servo system is occasionally needed for simple industrial application which precise and high control performance is not exessively important so that the cost production can be reduced efficiently.Simplified vector control,which has simple control structure,is utilized as the permanent magnet synchronous motor control algorithm and genetic algorithm is used to tune three PI controllers used in simplified vector control.The control performance is obtained from simulation and investigated to verify the feasibility of the algorithm to be applied in the real application.Simulation results show that the speed and torque responses of the system in both continuous time and discrete time can achieve good performances.Furthermore,simplified vector control combined with genetic algorithm has a similar performance with conventional field oriented control algorithm and possible to be realized into the real simple application in the future. | WIBOWO Wahyu Kunto JEONG Seok-kwon | 2013 | Journal of Central South University2013，20，11： | 11 |
| 2 | Improved estimation of rotor position for sensorless control of a PMSM based on a sliding mode observer显示文摘This work proposes a new strategy to improve the rotor position estimation of a permanent magnet synchronous motor(PMSM) over wide speed range. Rotor position estimation of a PMSM is performed by using sliding mode observer(SMO). An adaptive observer gain was designed based on Lyapunov function and applied to solve the chattering problem caused by the discontinuous function of the SMO in the wide speed range. The cascade low-pass filter(LPF) with variable cut-off frequency was proposed to reduce the chattering problem and to attenuate the filtering capability of the SMO. In addition, the phase shift caused by the filter was counterbalanced by applying the variable phase delay compensation for the whole speed area. High accuracy estimation result of the rotor position was obtained in the experiment by applying the proposed estimation strategy. | Wahyu Kunto Wibowo Seok-Kwon Jeong | 2016 | Journal of Central South University2016，23，7： | 8 |
| 3 | Optimal Tracking Controller Design for a Small Scale Helicopter显示文摘A model helicopter is more difficult to control than its full scale counterpart. This is due to its greater sensitivity to control inputs and disturbances as well as higher bandwidth of dynamics. This work is focused on designing practical tracking controller for a small scale helicopter following predefined trajectories. A tracking controller based on optimal control theory is synthe- sized as a part of the development of an autonomous helicopter. Some issues with regards to control constraints are addressed. The weighting between state tracking performance and control power expenditure is analyzed. Overall performance of the control design is evaluated based on its time domain histories of trajectories as well as control inputs. | Agus Budiyono Singgih S.
