中文摘要: 当异步电动机轻载或空载运行时,功率因数较低,适当调节异步电动机端电压,可以降低能耗实现节能.本文介绍一种基于R8CL38单片机的异步电动机自适应调压节能技术,以最优控制参考模型为基础,采用模型参考直接自适应方法进行控制.仿真计算结果表明该控制技术节能效果明显,性能稳定可靠.
Abstract:Three-Phase asynchronous motor’s power factor and efficiency are usually very low when the loads are free or light. Regulating the input voltage of motors properly can raise the power factor and reduce the losses, which is a kind of Energy-saving technology. This paper introduces an adaptive control method of three-phase asynchronous motors which is a kind of energy-saving technology based on R8CL38. The reference model with optimum control method is adopted. It can control the voltage of three-phase asynchronous motors directly. Simulation results show the designed energy-saving power controller is effective, and the control system is stable and reliable.
