摘要
为了提高PID算法的控制品质,在其基础上增加了加速度项,提出了PIDA控制算法。该算法提供了更大的超前相角,改善了系统阻尼特性和稳定性,但造成控制量过大。通过引入加权因子,构成加权PIDA控制,不仅有效改善了控制品质而且获得满意的控制信号。最后通过对比仿真实验验证了PIDA控制算法的有效性。
In order to improve the performance of PID control, a new control algorithm named PIDA is proposed by adding acceleration control to PID controller. Compared with PID controller, PIDA algorithm can provide more phase lead, more damping and system stability, but it cause big controller＇s output. Through introducing weighting factors, weight PIDA control is formed. The weight PIDA＇s performance and it＇s control signal are satisfied. At last, simulation examples were computed to show the validity of the mentioned method.
