摘要:

为解决现有煤矿皮带机传动系统占地空间大、传动效率低、维护频度高等问题,提出一种外转子永磁同步电机(outer-rotor PMSM)直接驱动结构,并将一种串级结构的无模型自适应控制算法应用到皮带机驱动电机的速度控制中。根据矿井皮带机的运行要求,给出该电机详细的设计参数和数学模型,设定了启动和稳态时的理想速度曲线。利用无模型自适应控制算法设计出串级无模型自适应控制律,并给出串级控制系统结构图。通过Matlab软件对外转子PMSM在煤矿皮带机的直驱伺服系统按照理想的启动“S”型曲线进行仿真,其结果表明:串级无模型自适应控制算法降低了速度跟踪误差,提高了调速控制精度,有效地抑制了系统噪声和负载变化带来的干扰,实现了皮带机良好的启动和稳态特性。

Abstract:

To solve the problems of large space, low transmission efficiency, high maintenance frequency in existing coal mine belt conveyor transmission system, a kind of direct drive structure using outer-rotor Permanent Magnet Synchronous Motor (outer-rotor PMSM) was proposed, and a model-free adaptive control with cascade structure was applied to the speed control system of belt conveyor. According to the requirements of mine belt conveyor running, the detailed design parameters and mathematical model of this motor were given, and the ideal speed curves of starting and the steady state were set. By using model-free adaptive control algorithm, a cascade model-free adaptive control law was designed, and the cascade control system structure was also given. The simulation of the ideal starting curve in direct-drive system in coal mine belt conveyor for outer-rotor PMSM was conducted using Matlab software. The results show that the cascade model-free adaptive control algorithm reduces the speed tracking error and improves control precision, which suppresses the system noise and the disturbance for load changing effectively. This method achieves good startup and steady-state characteristics of belt conveyor.
