Active control method for vibration of piezoelectric structure for adaptive narrow-band filtering

The invention relates to an active control method for vibration of a piezoelectric structure for adaptive narrow-band filtering. A swept-frequency signal of a narrow band is used as an identification signal; and compared with a conventional white noise signal, the swept-frequency signal has the advantages that the energy of the swept-frequency signal is more intensive, and a piezoelectric element can be effectively driven to realize full excitation of the structure and increase the signal-to-noise ratio of a response signal, to enhance the control effect of the whole control system. A main channel control algorithm adopts a step length change algorithm to update a step length factor, and a secondary channel also adopts a step length change updating algorithm during on-line identification. Compared with an adaptive fixed-step-length updating algorithm, the active control method has the advantages that the convergence speed of the algorithm is obviously improved, and a stabilization error value is further reduced. Due to the step length change algorithm, the speed and the precision of the on-line identification of the secondary channel are improved.

Low-noise stable permanent magnet switch reluctance motor and manufacturing process and heat dissipation method thereof

The invention relates to a low-noise stable permanent magnet switch reluctance motor and a manufacturing process and a heat dissipation method thereof. A permanent magnet circular ring is fixed to a rotor bracket of the motor, the permanent magnet circular ring is formed by an even number of stepped circular-arc-shaped permanent magnets in a head-tail oppositely matched mode, the magnetic polaritydirection of the circular-arc-shaped permanent magnets is radial, and the magnetic polarity of the adjacent circular-arc-shaped permanent magnets is different. When a double-magnetic-polarity cambered surface part section of the permanent magnet circular ring passes through a stator excitation salient pole pair, the change of magnetic acting force between the stator excitation salient pole pair and the rotor permanent magnet circular ring is obviously slowed down, and thus the motor operates more stably. Through the manufacturing process provided by the invention, a basic condition is createdfor improving the machining precision and the assembly efficiency of the motor. Various heat dissipation methods are ingeniously fused into overall design and manufacturing of the motor, convection heat dissipation of the motor structure, conduction heat dissipation of a metal material and heat-conducing heat dissipation of heat-conducting sealant are fully considered, and thus the optimal heat dissipation effect of the motor is achieved.
