Abstract

Location follow to move system again fit to follow systematic or servo system. It major solution has the location of certain precision that follows problem voluntarily, control work and the feed of cutting tool of machine tool in full too location control, the working movement of industrial robot, industry automatic Dao draw the sport of vehicle, the radar tracking on defence, missile system Dao, gun aim etc.. In modern computer integrated machine production system ( CIMS ) the fields such as flexible machine production system ( FMS ), location follow to move system get more and more extensive application. The emulation of control system is the important link that control system designs and analyses. MATLAB language and it's Simulink and Statrflow and various function type tool case have offered rich control system design analysis tool for us. It is calculated that this paper follows through exchanging location to move systematic MATLAB and emulation, combine the best computer emulation software MATLAB and control systematic two. Difference has introduced the relevant knowledge of control system and MATLAB. Aim at make use can pass through this software, fast analysis design control system uses and designs intelligent algorithm fast, fast optimization parameter, promoting MATLAB in home popularize application
Computer-aided analysis and design are carried out for speed-controlling system of d-c motor by using TOOLBOX AND SIMULINK.The result shows that this is an efficient andhigh-precision method suitable for design of the practical speed-controlling system.
