研究优化控制器设计问题,工业过程控制中广泛使用的PID控制器,参数的选取可等效为优化问题。针对PID控制器应用于实际的自动电压调节器(AVR)系统,为了有效地寻找AVR系统的最佳PID控制器参数,提出一种基于粒子群算法的PID参数优化策略。通过建立粒子群优化的PID控制器参数模型,在控制过程中将PID参数(比例、积分、微分)作为粒子群中的粒子,采用控制误差绝对值时间积分函数作为优化目标,在控制过程中动态调整PID的三个控制参数,从而进行PID控制参数的实时优化。仿真结果表明PID控制器可以获得较好的控制性能指标,进而改善AVR系统的瞬时响应特性,具有一定的实用价值。

以一种工业机器人为研究对象,在机器人运动学的基础上,分析其全域运动性能平均指标、全域运动性能波动指标、全域运动性能最差指标,并针对这3项性能指标进行多目标优化。将机器人杆长参数作为机构设计变量,根据机器人的工作空间及运动学灵活性要求建立多目标优化模型。设计一种改进的多目标粒子群算法,引入Pareto分布熵及其差熵估计种群的多样性及进化状态,以此为反馈信息来设计进化策略。进行优化计算,最终得到一组最优解。采用优化后的机器人机构参数可以使机器人运动灵活性能有较大提高。

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.
