Along with succeeding in developing of pulse-width modulation type (PWM) power amplifier, solved the contradiction between efficient and the power.The external PWM technology that adopts has produced integrated circuit component, such as Texas Instruments and the APEX company PWM type audio frequency power amplifier integrated circuit component that released one after another.The SA60 of APEX company, efficient can reach 97%, and output current reaches 10A.The different control methods such as Bang-Bang control, sampling retentive control and the control that lags behind are also used on the Design and implementation of close power amplifier of ten active magnetic bearing systems in succession.At present, close power amplifier develops to high-power, the SPAK close power amplifier of Britain LDS (Ling Dynamic System Ltd) company adopts a plurality of close power amplifier modules in parallel, peak output can reach 280kW, switching frequency 150kHz, efficient reaches 93%, but has equal flow problem between its module.Novel close power amplifier is attempting adopting dsp chip exploitation DPPC (digital pulse power converter), and its carrier frequency is variable, and frequency is up to megahertz.
At present, the continuous upgrading of ANSYS software can better be simulated for the analysis of finite element, to the analysis by magnetic field, thereby more effectively goes the variation of controlling magnetic field and on the impact of components and parts on every side.Can utilize simultaneously the three-dimensional magnetic field of ANSYS software simulation high speed electromagnetic damper electromagnet generation, thereby simulate the magnetic line of force distribution situation of electromagnet, then calculate the induction level between magnetic gap, the correctness of checking simulation.ANSYS can provide the distribution characteristics of electromagnet magnetic induction intensity total amount and component, realizes the visual of electromagnet magnetic field.
Adopt ADAMS that the electromagnetic damping vibration insulating system has been carried out vibration Simulation Analysis, can pass through simulation result, damping ratio rationally is set, can the establishment resonance peak, increase substantially the low frequency vibration damping effect, and can be on very little on vibration reduction platform resonant frequency and high frequency performance impact.Adopt ADAMS and MATLAB2 kind software and traditional PI D (proportion integration differentiation), incomplete differential PID and 3 kinds of controlling methods of fuzzy Self-Tuning of PID respectively to the motion simulation of system.
Therefore, the high integration high speed controllable damper that is made of electromagnet apparatus has possessed the possibility that realizes, can realize the able to programme quantitative control under the high speed operation, the using scope of the terminal damper that extended has reduced time of repeating to research and develop and the cost of commercial Application.
