The PID controller algorithm itself has few problems. Most problems arise from instrumentation connected to the controller. One common problem is "integral windup". It might take too long for the output value to ramp up to the necessary value when the loop first starts up. Sometimes this can be fixed with a more aggressive differential term. Sometimes the loop has to be "preloaded" with a starting output. Another option is to disable the integral function until the measured ...

Usually, Chaos Control is synonymous with teleportation, although it can affect reality in a multitude of manners. When used by the player, Chaos Control stops time or moves the player through the level at a high speed, often releasing bursts of energy. In Sonic Heroes, Chaos Control is part of Team Dark's Team Blast, "Chaos Inferno". When activated, the power stop the time of everything around them for a few seconds after the, Chaos Inferno". In Sonic Battle, all of Sh ...

Remote control - Industry. Remote control is used for controlling substations, pump storage power stations and HVDC-plants. For these systems often PLC-systems working in the longwave range are used. Remote control - Weapons. Remote controlled weapons have been used since World War II. Remote control - Space. Remote control technology is also used in space travel, for instance the Russian Lunokhod vehicles were remote-controlled from the ground. Direct remote control of space vehicles at greater distances from the earth is not practic ...

Terminal Control Centers are responsible for providing all ATC services within their airspace. Generally, there are four types of traffic flows controlled by Terminal Control Center controllers. These are departures, arrivals, overflights, and aircraft operating under Visual Flight Rules (VFR). Terminal Control Center - Departure aircraft. Departure aircraft are received from the tower and are generally 1,000 feet to 2,000 feet high, climbing to a pre-determined altitude. The Terminal Control Center contro ...

Some American Indians had rituals which they believed could induce rain. The Finnish people, on the other hand, were believed by others to be able to control all weather. Thus Vikings refused to take Finns on their raids by sea. Remnants of this belief lasted well into the modern age, with many ship crews being reluctant to accept Finnish sailors. The early modern era saw people observe that during battles the firing of cannons and other firearms often initiated precipitation. The fi ...

Since the controller is the most common way of interacting with a game, it has to be ergonomically designed to feel comfortable to most of their potential userbase to avoid injuries such as the ones in the RSI group or CTS. Most controllers these days are designed with the relaxed position of the hands in mind, which gave origin to the "horns" design that reduced the soreness and cramping after extended use with ol ...

Many programming languages, particularly those which favor more dynamic styles of programming, offer constructs for non-local control flow. These cause the flow of execution to jump out of a given context and resume at some predeclared point. Exceptions, conditions, and continuations are three common sorts of non-local control constructs. Control flow - Conditions in PL/I. PL/1 has some 22 standard conditions (e.g. ZERODIVIDE SUBSCRIPTRANGE ENDFILE) which can be RAISEd and which ...

The Fat Controller might best be described as a "firm but fair" leader. He acts as a sort of parent to the engines of Sodor. He does not stand for any nonsense, but he is also forgiving. When an engine misbehaves, as they often do on his railway, he is willing to allow them a second chance if they are truly sorry. He is also quite perceptive and shrewd, and is not above using elaborate schemes to get to the bottom of a problem. In his first appearance, in 'The Sad Story of Henry', he was a rather more pompous and lazy figure. By the next book, 'Thomas the Tank En ...

In May 1966, Böhm and Jacopini published an article in Communications of the ACM which showed that any program with gotos could be transformed into a goto-free form involving only choice (IF THEN ELSE) and loops (WHILE condition DO xxx), possibly with duplicated code and/or the addition of Boolean variables (true/false flags). Later authors have shown that choice can be replaced by loops (and yet more Boolean variables). The fact that such minimalism is possible does not necessarily mean that it is desirable; after all, comput ...

Control Room - Al Jazeera's role in Arab society. The film documents the spectrum of opinion that surrounds the Qatar television news network Al Jazeera. Throughout the film Donald Rumsfeld appears at press conferences, complaining about the propagandist nature of Al Jazeera. Paradoxically, a clip of Baghdad Bob shows him challenging the organization to "stop (its) propaganda!" The contrasting views between the documentary’s central figures are not so clear cut. Early in the movie, press officer Lt. Rushing rem ...

One of the earliest examples of remote control was developed in 1893 by Nikola Tesla, and described in his patent, U.S. Patent 613809, named Method of and Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles. The first remote controlled model airplane flew 1932. The use of remote control technology for military purposes was worked intensively during the Second World War, one result of this was the German Wasserfall missile. The first remote intended to control a television was developed by Zenith Radio Corporation in the ...

Fuzzy logic is an attempt to get the easy design of logic controllers, and yet control continuously-varying systems. Basically, a measurement in a fuzzy logic system can be partly true, that is, if yes is 1, and no is 0, a fuzzy measurement can be between 0 and 1. The rules of the system are written in natural language, and translated into fuzzy logic. For example, the design for a furnace would start with: "If the temperature is too high, reduce the fuel to the furnace. If the temperature ...

Since modern small computers are so cheap (often less than $1 US), it's very common to implement control systems, including feedback loops, with computers, often in an embedded system. The feedback controls are simulated by having the computer make periodic measurements, and then calculating from this stream of measurements (See digital signal processing). Computers emulate logic devices by making measurements of switch inputs, then calculating a logic function, then s ...

Given the number of mobile and soft rubber parts in controllers it can be expected that after extensive use, some of the buttons will become eventually less responsive due to the softening of the rubber parts that connect the hard exterior button to the integrated circuit. Even the plastic outer casings of joysticks and wheels might crack if used too violently. This becomes more of an issue with cheaper third-party controllers. Button mashing and joystick wobbling were responsible for countless broken controllers until the mid of the 16-bit ...
