Abstract

In Scheme Of Control System Supervise The, Knowledge Hit In Control System Play RoleVery Important. Scheme Problem Become Complicated Progressively If Supervision Of ResultOf Design Of Specification Base Of System Wanted By Designer Cannot Prevent TheUndesirable Process. Solution For The Matter Of Like This Claim The Knowledge Hit InControl System And Specification Of System Wanted In More Circumstantial. In This PaperWill Study The Method Development In Control System Through Development OfSpecification Of System, So That The Specification Of System Reached By Paying Attention ToSystem Security. The Development Of Controllability System Method Through DevelopmentOf Specification Of The System Later Then Application To Design The SupermarketSupervisionKeywords: Controllability System, Supervise, Extended Controllable System

Abstract

Generally, the design of control system begins with plant modeling. The analytical systemmodeling through physical observation is usually dificult to be obtained.Therefore, theexperimental system model become main stay alternative. This paper presents the process ofsystem parameters estimation. The methode of parameters estimation are use“PROGRESIVE ITEGRATION METHODE”. The resulted of parameters estimation thenbe simulated to computer with used MATLAB software version 5.3. From the result ofsimulation can be showed that the change of system parameters only influencial systemresponnse if the happen of parametera change on the moment transient state systemKeywords: parameter estimation, progressive integration and simulation

Abstract

The best resulted of feedback control system design by using state variable feedback. But notall of the state variables feedbacks are available. The solution of this problem is useestimator. Through input and output measurements, then drive to estimator so can requiredoutput estimator near state variable.This paper presents the estimator design through artificial control model. So that todetermined the gain estimator and simulated using by software MALAB version 6.5. Theexperiment to carry out by three replicated of simulations with difference estimator gain.The good design will be achieved if estimator gain to caused that transient time estimatormore fast then transient time plant.Keywords: estimator, state variable, state variable feedback1.

Abstract

Digital computers are available not only for design of control system but also to perform thecontrol function. Advances in digital computers and microprocessors have made their usevery attractive as components in control system. Using digital computer with a plantoperating in the continuous-time domain requires that its input signal be discrete, which inturn requires the sampling of the signals used by the controller. An A/D converter must beincorporated in the digital control system. This paper presents the choice of sampling timeand bit numbers and they’re to the system characteristics. An example of the calculation ofsampling time an. their results are presented in the paper.Keywords: digital computer, sampling theorem and A/D converter.1. Pendahuluan

Abstract

The design of feedback control system still using pole placement until now. Therefore theinformation of system parameters was required. One of the way to obtained information ofsystem parameters by system parameter estimator. This estimation process is required thecolection of input-output data. Input-output data can obtained from natural system(unspecify generated). This paper present estimator design using random input (not stepfunction). Estimation method using “Least Square”. The resulted of simulator design wassimulated. From this simulation of parameter estimator is good result indicated.Keywords: feedback, control system, estimator, Least Square.
