【摘要】 在液压APC(Autom atic Position Control)系统中,由于存在控制干扰和测量噪声,为了达到控制精度,通常采取低通滤波,但效果不甚理想。为此,本文提出了一种基于卡尔曼滤波器的控制方法,该方法采用时域上的递推算法进行数字滤波处理,通过仿真和实际应用证明该方法使APC系统运行平稳,大大提高了APC系统的精度。更多还原

【Abstract】 Because of control interference and measurement noise,lowpass filter is generally used to reach control precision in hydraulic APC system.But its effect is not satisfying. A control method based on Kalman filter which adopts temporal recurrence algorithms for digital filtering was put forward.Simulation and application proved that the method made APC system run reposefully,and improved APC precision.更多还原
