RESEARCH ON AN NEW ADAPTIVE INFERENTIAL CONTROL CVCF POWER SUPPLY

针对CVCF交流电源系统这样一个输出可测,而负荷扰动不可测的系统推理控制器数学模型的建立及其自适应问题进行了分析、讨论和研究;在推理控制器的设计中,提出了一种简化的等效设计方法,获得了在物理上可以实现的推理控制器模型。由于CVCF交流电源系统其对象是具有非线性和时变性的,为了获得良好的动态响应,使系统具有更强的鲁棒性,在上述研究的基础上,通过建立参数估计模型来实现推理控制器的自适应控制。理论分析和仿真实验结果证明了该文所研究的自适应推理控制设计方法应用于CVCF交流电源系统的有效性,系统在动态响应、抗干扰能力、增强鲁棒性等获得了令人满意的结果。介绍了应用新型芯片DSP-ADMC331设计和实现CVCF交流电源自适应推理控制系统,其有着广阔的应用前景。

This paper discussed the modeling and the problem of adaption of CVCF power supply system which had measurable outputs and unmeasurable load disturbance.Asimplified and equivalent design method was put forward during the designation of inferential controller and a realizable model of inferential controller was obtained in physics.As the object of CVCF power supply system was nonlinear and time-varying and in order to get good dynamic response and strongerrobustness,adaptive control of inferential control was realized by building parameter estimate model.Theoretical analysis andsimulation results demonstrate the effectiveness of adaptiveinferential control in CVCF power supply system.The system has got a satisfactory result of dynamic response、strong anti-interference and strong robustness.The paper also introduced the design and realization of CVCF power supply control system by using chip DSP-ADMC331 which had wide application prospects.
