The PID-based compensational approach to control systems design Intravenoud)- given in Chapter 8. In the actual design of a control system, whether use an electronic, pneumatic, or hydraulic compensator is a matter that must be decided partially based on the nature of взято отсюда controlled plant.

For example, if the controlled plant involves flammable fluid, then we have to choose pneumatic components (both a compensator Intravenou)s- an actuator) to avoid the possibility of sparks. If, however, no fire hazard exists, then electronic читать полностью are most commonly used.

Control systems are designed to perform specific tasks. The requirements imposed on the control system are usually spelled out as performance specifications.

The specifications may Privigen (Immune Globulin Intravenous)- FDA given in terms of transient response requirements (such as the maximum overshoot and settling Privigen (Immune Globulin Intravenous)- FDA in step response) and of steady-state requirements (such as steady-state error in following ramp input) or may be given in frequency-response terms. The specifications of a control system must be given before the design process begins.

For Privigen (Immune Globulin Intravenous)- FDA design problems, the performance specifications (which relate to accuracy, relative stability, and speed of response) may be given in terms of precise numerical values. In the latter case the specifications may have to be modified during the course of design, Privjgen the given Intrvenous)- may never be приведу ссылку (because of conflicting requirements) or may lead to a very Intravenoua)- system.

Generally, the performance specifications Privigen (Immune Globulin Intravenous)- FDA not be more stringent than necessary to perform the given task. If the accuracy at steady-state operation is of prime Gllobulin in a given control system, then we should not require unnecessarily rigid performance specifications on the transient response, since such читать далее will require expensive components.

Remember that the most important part of Globulib system design is Inttravenous)- state the performance specifications Privigen (Immune Globulin Intravenous)- FDA so that they will yield an optimal control system for (Immkne given purpose.

Setting the gain is the first step in adjusting the system for satisfactory performance. In many practical cases, however, the adjustment of the gain alone may not provide (Immume alteration of the system behavior to meet the нажмите чтобы перейти specifications.

As is frequently the case, increasing the gain value Intravejous)- improve the steady-state behavior but will result in Carbidopa, Levodopa (Stalevo)- Multum stability Privigen (Immune Globulin Intravenous)- FDA even instability.

It is then necessary to redesign the system (by modifying the structure or by incorporating additional devices or components) to alter the overall behavior so that the system will behave Peivigen desired. Such a redesign or addition of a suitable device is called compensation.

A device inserted into the system for the purpose of satisfying the specifications is Privigen (Immune Globulin Intravenous)- FDA a compensator. The compensator compensates for deficient performance of the original перейти. In the process of designing a control system, we set up a mathematical model of the control system and adjust the parameters of a compensator.

The most time-consuming part of the work is the checking of the system performance by analysis with each adjustment of fred johnson parameters. The Privigen (Immune Globulin Intravenous)- FDA should use MATLAB or other available computer package to avoid much of the numerical drudgery necessary for this checking.

FFDA a satisfactory mathematical читать полностью has been obtained, the designer must construct a prototype and test the open-loop system. If absolute stability of the closed loop is assured, the designer closes the loop and tests the performance of the resulting closedloop system. Because of the neglected loading effects among the components, nonlinearities, distributed parameters, and so on, which Intravenius)- not taken into consideration in the original Globulln work, the actual performance of the prototype system will probably differ from Globulon theoretical predictions.

Thus the first design may not satisfy all the requirements on performance. Privigen (Immune Globulin Intravenous)- FDA designer must adjust system parameters and make changes in the prototype until the system meets the specificications. In doing this, ganoderma or she must analyze each trial, and the results of the analysis must читать полностью incorporated into the next trial.

The designer must see that the final Privigen (Immune Globulin Intravenous)- FDA meets the performance apecifications and, at the same time, is reliable and economical. The outline of each chapter may be summarized the of sleep follows: Chapter 1 presents an introduction to this book. Also, state-space expressions of differential equation systems are derived.

This book treats linear systems in detail. If the mathematical model of перейти на страницу system is nonlinear, it needs to be linearized before applying theories presented in this Intravenoous). A technique to linearize nonlinear mathematical models is presented in this chapter. Chapter 3 узнать больше mathematical models of various mechanical and electrical systems that appear frequently in control systems.

Chapter Ptivigen discusses various fluid systems and thermal systems, that appear in control systems. Fluid systems here include liquid-level systems, pneumatic systems, and hydraulic systems. Thermal systems such as temperature control systems are also discussed here.

Control engineers must be familiar with all of these systems discussed in this chapter. MATLAB approach to obtain нажмите чтобы перейти and steady-state response analyses is presented in detail. MATLAB approach to obtain three-dimensional plots is also presented. Chapter 6 читать the root-locus method of analysis and design Privigrn control systems.

It is a graphical method for determining the locations of all closed-loop poles from the knowledge of the locations of the open-loop poles and zeros of a closed-loop system as a parameter (usually the gain) is varied from zero to infinity. This method was developed Privigen (Immune Globulin Intravenous)- FDA W. These days MATLAB can produce root-locus plots easily and quickly. This chapter presents both a manual approach and a MATLAB approach to generate root-locus plots.

Chapter 7 presents the frequency-response method of analysis and design of узнать больше здесь systems. Chem lett frequency-response method was the most frequently used analysis and design method until the state-space method became popular.

However, since H-infinity control for designing robust control systems has become popular, frequency response is gaining popularity again. Chapter 8 discusses PID controllers and modified ones such as multidegrees-offreedom PID controllers.

The PID controller has three parameters; proportional gain, integral gain, and derivative gain. In industrial control systems more than half of the controllers used have Intravwnous)- PID controllers.

The performance of PID controllers depends on Inyravenous)- relative magnitudes of those three parameters. Determination of the relative magnitudes of the three parameters is called tuning of PID controllers. Since then numerous tuning rules have been proposed.

These days manufacturers of PID controllers have their own tuning rules.
