摘要
搜索雷达方位伺服控制系统不平衡力矩及阵面风阻力矩具有时变、非线性的特点,影响控制系统的稳定性与控制精度,传统的PID控制不能有效抑制干扰,因此设计了一种积分滑模控制算法并建模进行仿真实验,结果表明设计的积分滑模控制算法具有较快的动态响应及较强的干扰抑制能力,为工程应用奠定了基础。
The unbalanced torque and wind resistance torque of the azimuth servo control system of the search radar are time-varying and nonlinear,affecting the stability and control accuracy of the control system.The traditional PID control method can not effectively suppress the interference.Therefore,an integral sliding mode control algorithm is designed and verified by modeling and simulation.The results show that the designed sliding model control algorithm has a faster response speed and better interfer⁃ence suppression,laying a foudation for engineering application.
