摘要
对于解决平面四杆机构轨迹综合等复杂非线性约束优化问题,传统优化算法存在局部收敛等缺点。对混沌的特性及其优化应用进行了分析,建立了混沌结合传统Powell法的混合算法。设计实例表明,该方法全局收敛性好,搜索效率高,是解决工程设计中具有复杂非线性约束优化特性问题的理想方法。
To solve path generation synthesis of planar 4-bar linkage which is a complex nonlinear constraint problem, traditional optimizations have disadvantages such as local convergence. Features of chaos and its applications to optimization are analyzed, and a mixed chaos optimization combining Powell method is found. The examples indicate that the algorithm has excellent convergence property and high efficiency and is a good method to solve complex nonlinear constraint engineering problems.
