电池充电过程具有非线性和滞后性。比例积分微分控制是蓄电池充电过程中常用的控制方法。控制效果由PID控制参数${K}_p$、${K}_i$和${K}_d$决定。传统的PID参数整定方法很难给出合适的参数,影响了电池的充电效率。本文将粒子群优化算法(PSO)应用于PID参数的优化。针对基本粒子群算法收敛速度慢、收敛精度低、易早熟等缺点,提出了一种改进的粒子群优化算法,并将优化后的PID参数应用于电池充电控制系统。实验结果表明,电池充电过程具有较好的动态性能,电池充电效率从86.44%提高到91.47%,充电温升降低了1°C。
The battery charging process has nonlinear and hysteresis properties. PID (Proportion Integration Differentiation) control is a conventional control method used in the battery charging process. The control effect is determined by the PID control parameters ${K}_p$,  ${K}_i$  and  ${K}_d$. The traditional PID parameter setting method is difficult to give the appropriate parameters, which affects the battery charging efficiency. In this paper, the particle swarm optimization (PSO) is used to optimize the PID parameters. Aiming at the defects of basic PSO, such as slow convergence speed, low convergence precision and easy to be premature, a modified particle swarm optimization algorithm is proposed, and the optimized PID parameters are applied to the battery charging control system. Also, the experimental results show that the battery charging process possesses better dynamic performance and the charging efficiency of the battery has increased from 86.44% to 91.47%, and the charging temperature rise has dropped by 1°C.
