Control System Pdf

P R E V I E W. In this chapter, we describe a general process for designing a control system. A con- examples of control systems through the course of history. Time Domain Performance Analysis of Linear Control Systems For example, a control system often includes electrical, mechanical and chemical. This is an example of a closed loop Control System. Control A control system can be thought of as any system where additional hardware.

Skip to main content. Log In Sign Up. Devasena A. What is meant by a system? It is an arrangement of physical components related in such a manner as to form an entire unit. What is a command input? It is the excitation applied to a control system from an external source. It is also a motivating input signal to the system, which is independent of the output of the system. Define output. It is the actual response obtained from a control system, which must be maintained at a prescribed value. What is an actuating signal? It is the difference between the reference input and feedback signal. It is also called as actuating signal. Define plant. List the two types of control systems?

Unlock: Upon validation, the presenter can unlock whatever she wants to access. This can happen by pushing a button, presenting an access card, fob, or badge that requests access. Trigger: Once the request to enter has been received by the access control system, the access is triggered, typically in the form of a door unlock.

Infrastructure: If the door unlocks, multiple events are tracked at once: The user was correctly authenticated, the user triggered an unlock, the door opened and the door closed.

Scale: Cloud-based access control systems can help startups and small businesses when they expand to new offices or additional offices by providing flexible and modular extensions of the existing setup.

Monitor: Online access control systems send real-time alerts to administrators or security should any irregularity or attempted breach take place at any access point, allowing them to investigate immediately and record the event.

Troubleshoot: Modern access control systems allow administrators to remotely configure permissions, or seek support from the vendor, should access points or users have issues—a huge advantage over locally-hosted systems.

In addition, it helps certain sectors meet special requirements. Scale: Businesses can perform regularly-scheduled system reviews to make sure everything on the access control system is set up properly. It can also tell them if someone no longer employed by the company has been inadvertently left in the system. Suspicious Events: Since many access points are routinely tracked during any access event, auditing can prove useful to security officers when investigating unusual behavior.

The data can be used to flag or highlight unusual access behavior or analyze it against historical data.

Compliance Reports: Companies that process sensitive data like patient healthcare information, banking financial reports, or credit card payments must deal with audit requirements in the access control space when filing compliance reports in accordance with HIPAA, SOC2 or PCI.

Some special categories like cyber security or ISO certifications also require managed and auditable access control. The audit phase can pull up the proper data for these periodic reports. This can create confusion for anyone charged with outfitting their facility with one—but if they take it step by step, everything will come together. The first step a company should take is obvious—do a count of all the doors that need to be secured; not just the entry doors, but also IT room doors where expensive equipment and security-related devices are installed, and for companies handling sensitive healthcare or financial data, the file rooms or offices where computers processing this data are kept.

Once this has been done, a team should be charged with looking into options, researching vendors, and getting bids. Traffic control at intersections is a matter of concern in large cities.
