这是本人夏季学期的课程设计：模拟信号数字化滤波处理的计算仿真-Chebyshev I型低通滤波，对模拟信号进行数字化滤波处理。根据数字滤波器的性能指标，计算出Chebyshev1型低通IIR数字滤波器的系统函数，画出数字滤波器的频率响应曲线，给出Chebyshev1型低通IIR数字滤波器的设计结果。(This is my summer semester of the curriculum design: analog signal processing digital simulation filtering-Chebyshev I-type low-pass filtering, on the analog signal to digital filter processing. Digital filter in accordance with performance indicators, calculated Chebyshev1-type low-pass IIR digital filter systems function, to draw the digital filter frequency response curve, give Chebyshev1 type low-pass IIR digital filter design.)

该算法是以粒子群中粒子的收敛特性为基础,依据量子物理理论提出的,改变了传统粒子群算法的搜索策略,可使粒子在整个可行解空间中搜索寻求全局最优解。同时该算法的进化方程中不需要速度向量,而且进化方程的形式更简单,参数较少且容易控制。对两个算例进行仿真测试,证实该算法可有效解决经济负荷分配问题 性能对比显示,该算法求得的解优于已有的改进粒子群算法及其它优化算法所求得的解。(The algorithm is based on convergence particle swarm particle basis, according to the theory of quantum physics, particle swarm algorithm has changed the traditional search strategies, allow the particles throughout the feasible solution space search seek the global optimal solution. Meanwhile, the algorithm does not need velocity vector evolution equations, and evolution equations simpler and less parameters and easy to control. Two examples of simulation tests confirmed that the algorithm can effectively solve the economic load allocation performance comparison shows that the algorithm is superior to existing solutions obtained improved PSO algorithm and other optimization algorithms obtained solution.)
