参数自寻优的伪微分调节器的设计和应用

The Design and Application of a Simulated Differential Adjustor with Auto Parameter Optimization

控制系统设计常常要加入调节器以满足一定的性能要求.该环节的选择、参数的正确与否对系统性能影响很大.一般PID调节器的控制算法与结构较为简单,在工程上有着广泛应用,但它存在不可忽略的缺点,其参数整定的方法也较为复杂.于是从参数优化的角度结合MATLAB仿真软件,依照改进的性能指标(目标函数)自动选出所设计调节器的优化参数,以查表的形式将它们应用在具有转子参数自适应的非线性微分几何解耦控制系统中.结果表明:这种参数优化设计方式的使用具有良好的控制效果和一定的实用价值.

An adjustor is generally used in the design of a control system to meet the requirements of the performance. Its work and parameters produce great effect into a system. The PID adjustor has been widely applied in engineering project field for the simplicity of its arithmetic calculation and its structure. But it has fatal flaws and complicated parameter working. This paper discussed an adjustor design according to parameter optimization. The optimized parameters of the designed adjustor was automatically chosen according to improved function criteria （ target function） by using MATLAB. The rotor parameter self-adaptation was also adopted. All those were applied into an AD system with nonlinear decoupling. The result of the simulation indicates that design on parameter optimization produces good controlling effect to be applied in reality.
