Abstract
With development of all kind of science technology and global economy, Pneumatic manipulator is a automated devices that can mimic the human hand and arm movements to do something，aslo can according to a fixed procedure to moving objects or control tools. It can replace the heavy labor in order to achieve the production mechanization and automation, and can work in dangerous working environments to protect the personal safety.
Therefore widely used in machine building, metallurgy, electronics, light industry and atomic energy sectors.The pneumatic part of the design is primarily to choose the right valves and design a reasonable pneumatic control loop, by controlling and regulating pressure, flow atcompressedneceengththdirectionprocedurework.The inverted pendulum is a typical high order system, with multi variable, non-linear, strong-coupling, fleet and absolutely instable. It is representative as an ideal model to prove new control theory and techniques. During the control process, pendulum can effectively reflect many key problems such as equanimity, robust, follow-up and track, therefore.This paper studies a control method of double inverted pendulum . First of all, the mathematical model of the double inverted pendulum is established, then make a control design to double inverted pendulum on the mathematical model, and determine the system performance index weightmatrix , by using genetic algorithm in order to attain the system state feedback control matrix. Finally, the simulation of the system is made by . After several test matrix value the results are not satisfactory response, then we optimize matrix by using Genetic Algorithm. Simulation results show.The system response can meet the design requirements∮32 after Genetic Algorithm 335Mpa. Small twisted paper 37 machine for ordinary home, not only can be used for 5 meat, can also be used with crushed 15 meter, crushed ice, spices and otherfood, small power requirements, powered by the motor drive, reasonable structuredesign.
