无约束优化问题，对新手有一定的帮助作用，希望大家共同交流(Unconstrained optimization problem, certainly helps the novice role, I hope you and share their)

使用PID算法与FUZZYPID算法仿真并作比较，仿真证明，FUZZYPID效果要好于单纯PID调节(Using the PID algorithm and FUZZYPID algorithm simulation and compare simulation results show, FUZZYPID is better than the simple PID regulator)

Particle swarm optimization has been used to solve many optimization problems since it was proposed by Kennedy and Eberhart in 1995 [4]. After that, they published one book [9] and several papers on this topic [5][7][13][15], one of which did a study on its performance using four nonlinear functions adopted as a benchmark by many researchers in this area [14]. In PSO, each particle moves in the search space with a velocity according to its own previous best solution and its group’s previous best solution. The dimension of the search space can be any positive integer.

When I first studied Kalman filtering, I saw many advanced signal processing submissions here at the MATLAB Central File exchange, but I didn t see a heavily commented, basic Kalman filter present to allow someone new to Kalman filters to learn about creating them. So, a year later, I ve written a very simple, heavily commented discrete filter.

The code provides analysis of speech signals for communication
