Recently, the penetration of photovoltaic (PV) power in power system has being promoted rapidly. However, the PV power shows drastic fluctuation which presents great challenge to the power grid. Thus, how to mitigate the fluctuation of PV station needs to be solved. Battery energy storage system (BESS) is flexible to charge/discharge and track the fluctuation of PV power, and also BESS integrated...
This paper develop a named fuzzy switched multi-model algorithm for marine vessel. The rudder angle is used to divide the course changing process into multiple local operating regimes. The local controller is designed in local operating regime by using parallel distributed compensate method. The proposed algorithm can improve the global control performance in course-changing within wide range. The...
The single freedom magnetic levitation ball system is the base of magnetic products, it is essential to study the magnetic levitation ball system. In this paper, preliminary researches are conducted by analyzing the magnetic levitation ball systempsilas working principle and deriving the mathematical model in detail. After linearizing and analyzing the non-linear model, we proposed a fuzzy PID controller...
Because of the perturbations and disturbances of electro-hydraulic servo systems, the normal controller can't obtain good output responses under various conditions. The sliding mode control (SMC) based on fuzzy logic was presented for the system, and this approach can adjust parameters of reaching law at real time. Simulation results show that the improved system has nice robustness, and it is not...
