【摘要】：永磁同步电机(permanent magnet synchronous motor,PMSM),因其结构简单、运行可靠度高和维护方便等诸多优点,在伺服系统中成为使用最多的电机之一。本文基于信号与能量变换观点,系统地建立PMSM驱动系统的协调控制原理。文中将PMSM驱动系统认为是信号与能量变换装置,通过向系统输入信号和能量来改变控制系统的状态,并给出了PMSM驱动系统的信号控制器、能量控制器以及协调控制策略的设计过程与设计方法。第一,首先介绍了本课题的研究目的和意义。然后,介绍了PMSM速度伺服系统以及基于信号与能量协调控制方法的国内外研究动态。第二,初步研究了PMSM速度的滑模与端口受控哈密顿(port-controlled Hamiltonian,PCH)协调控制。分别求取滑模控制器和PCH控制器,采用协调控制策略将两种方法联系起来,仿真结果表明,采用该方案后,系统跟踪信号的快速性良好,同时也具有较好的稳态性能,初步证实了协调控制策略的可行性。第三,主要研究了PMSM速度的反步法与最大输出功率协调控制。为提高PMSM速度控制系统的性能,利用反步法解决系统的快速响应问题,应用最大输出功率原理使电机输出最大功率,采用指数函数作为协调函数来实现协调控制策略,从而适应PMSM的负载扰动。仿真结果表明,此方案有效地结合了反步法和最大输出功率原理的端口受控哈密顿协调控制的优点,使系统的动态性能和稳态性能优良,能够在负载扰动时使误差快速趋于零且输出功率最大。第四,主要探究了考虑损耗的PMSM速度系统的协调控制。采用考虑损耗的PMSM数学模型分析设计反步法控制器和PCH控制器,采用协调控制策略改善各个控制方法在不同时间段的作用力度。结果表明,系统响应快速且损耗最小。综上,为改善系统的动态、稳定性能,降低系统的损耗,本文采取基于信号与能量协调控制的方法设计系统控制器和协调控制策略实现对电机的速度控制。信号控制器实现PMSM驱动系统的速度信号快速跟踪控制,使系统具有快速动态性能。能量控制器实现PMSM驱动系统的稳态性能和能量优化控制,根据电机负载大小,实时优化控制系统的输入输出能量,并使系统的损耗能量最小。
[Abstract]:Permanent magnet synchronous motor (permanent magnet synchronous motor,PMSM) has become one of the most widely used motors in servo system because of its simple structure, high reliability and easy maintenance. Based on the viewpoint of signal and energy transformation, this paper systematically establishes the coordinated control principle of PMSM drive system. In this paper, the PMSM drive system is considered as a signal and energy conversion device. The state of the control system is changed by input of the signal and energy to the system. The signal controller of the PMSM drive system is given. Design process and method of energy controller and coordinated control strategy. Firstly, the purpose and significance of this research are introduced. Then, the PMSM speed servo system and the research trends based on signal and energy coordination control methods are introduced. Secondly, the sliding mode and port controlled Hamiltonian (port-controlled Hamiltonian,PCH) coordination control of PMSM speed are studied preliminarily. The sliding mode controller and the PCH controller are obtained, and the two methods are connected by the coordinated control strategy. The simulation results show that the tracking signal of the system is fast and has good steady-state performance. The feasibility of coordinated control strategy is preliminarily verified. Thirdly, the inverse step method of PMSM speed and the coordinated control of maximum output power are studied. In order to improve the performance of the PMSM speed control system, the rapid response problem of the system is solved by using the backstepping method. The principle of maximum output power is applied to make the motor output the maximum power, and the exponential function is used as the coordination function to realize the coordinated control strategy. In order to adapt to the load disturbance of PMSM. The simulation results show that this scheme effectively combines the advantages of the backstepping method and the principle of maximum output power of the port controlled Hamiltonian coordinated control, and makes the dynamic and steady performance of the system excellent. It can make the error fast to zero and the output power maximum when the load is disturbed. Fourthly, the coordinated control of PMSM speed system considering loss is discussed. The PMSM mathematical model considering loss is used to analyze and design the backstepping controller and the PCH controller. The coordinated control strategy is used to improve the action of each control method in different time periods. The results show that the response of the system is fast and the loss is minimum. In order to improve the dynamic and stable performance of the system and reduce the loss of the system, this paper adopts the method of signal and energy coordination control to design the system controller and coordinate control strategy to realize the speed control of the motor. The signal controller realizes the fast tracking control of the speed signal of the PMSM drive system, which makes the system have fast dynamic performance. The energy controller realizes the steady-state performance and energy optimization control of the PMSM drive system. According to the load size of the motor, the input and output energy of the system is optimized in real time, and the energy loss of the system is minimized.
