The permanent magnet synchronous motor (PMSM) with high efficiency, high power factor, high control accuracy, high torque inertia, larger speed range and good torque smoothness, and a series of advantages, is playing a very important role in AC servo system. Based on vector control, a PI controller is designed to improve the control performance of permanent magnet synchronous motor. In order to realize...
In direct drive XY table system, due to the load disturbance and parameter variation and parameter mismatch between the two axis of uncertainty factors will affect the contour machining precision, adaptive zero phase error tracking controller (ZPETC) combined with internal model control (IMC) control strategy is presented to control the tracking error, and cross-coupling control method is used to...
By merging the feed forward neural network, the competitive learning algorithm and the fuzzy control, the neural network-based adaptive fuzzy control algorithm is proposed. This system can produce more reasonable fuzzy rules by the competitive (clustering) algorithm, and control the object by the optimized fuzzy rules. The analysis of the system, the experimental result and considerations are given.
Along with the development of science and technology, information technologies have been used in many fields. Energy problem is a social focus nowadays. Energy-saving and environmental protection is the policy of China. According to our national conditions, road lighting system of our country is still emerging technologies. In this paper, to reach the purpose of energy saving, it introduces an information...
Q-Learning can successfully solve the congestion problem of isolated intersection. But it is not available to realize the coordination between two intersections. A switching-model of two intersections is introduced in this paper. The concept of combinative phase is put forward in order to divert two intersections into a single one. In this way, we can apply Q-Learning on two adjacent intersections...
