Control theory
Control theory is an interdisciplinary branch of engineering and mathematics that deals with the behavior of dynamical systems with inputs, and how their behavior is modified by feedback. The usual ...

Optogenetics: Controlling the brain with light
(04:50) This animation illustrates optogenetics -- a radical new technology for controlling brain activity with light. Ed Boyden (http://mcgovern.mit.edu/principal-investigators/ed-boyden), the co-in...
Amazing Resonance Experiment!
So this experiment is the Chladni plate experiment. I used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker.
20 Gadgets Which Make Life Simpler
Every day, we come up against annoying things that no one has ever found a way to resolve which works all the time. But in some cases, thanks to human ingenuity we are moving towards this. Here are 20...
How Funny Is This Word? The 'Snunkoople' Effect
How do you quantify something as complex and personal as humour? University of Alberta researchers have developed a mathematical method of doing just that—and it might not be quite as personal as we t...
How The Brain Controls Sleep
Sleep is usually considered an all-or-nothing state: The brain is either entirely awake or entirely asleep. However, MIT neuroscientists have discovered a brain circuit that can trigger small regions ...
Ethical Trials, Targeted Ads
New method optimizes outcomes for subjects in comparison tests. Clinical trials of new drugs or devices face a problem that most empirical inquiries don’t: They must not only provide clear data about ...
Sonogenetics: Sound Waves Successfully Used To Control Brain Cells
Scientists say simulating neurons with ultrasound is less invasive than light-based optogenetics. Sound waves have been used to control brain cells for the first time by scientists in California. Dubb...
Frog study suggests context matters when choosing a mate
The presence of a third option acts as a "decoy effect," inspiring a female frog to consistently select the less attractive of the two original options.
The 12 cognitive biases that prevent you from being rational
The human brain is capable of 1016 processes per second, which makes it far more powerful than any computer currently in existence. But that doesn't mean our brains don't have major limitations. The l...
Elon Musk, Stephen Hawking Letter Opposing Autonomous Weaponry
More than a thousand artificial-intelligence researchers have cosigned an open letter calling for a ban on autonomous weapons, or "killer robots." As The Verge reports, they have been joined by hundre...
Revolutionizing A Revolutionary Technology
Optogenetics, a technology that allows scientists to control cells with light, has blown the doors wide open in neuroscience since its debut less than a decade ago. With a new $1-million grant from th...
Recalling Happier Memories Can Reverse Depression
“Once you identify specific sites in the memory circuit which are not functioning well, or whose boosting will bring a beneficial consequence, there is a possibility of inventing new medical technolog...
'Shallow, Selfish, and Self-Absorbed' Details Why Women Aren't Having Children
As detailed in essays by 16 different writers, both male and female: because they don't want to, and because not wanting to is perfectly reasonable But there’s one issue that can make even Cool Pope F...
Researchers Find “Lost” Memories
Memories that have been “lost” as a result of amnesia can be recalled by activating brain cells with light. In a paper published today in the journal Science, researchers at MIT reveal that they were ...
Controllability
Controllability is an important property of a control system, and the controllability property plays a crucial role in many control problems, such as stabilization of unstable systems by feedback, or ...
Observability
In control theory, observability is a measure for how well internal states of a system can be inferred by knowledge of its external outputs. The observability and controllability of a system are mathe...
Closed-loop transfer function
A closed-loop transfer function in control theory is a mathematical expression (algorithm) describing the net result of the effects of a closed (feedback) loop on the input signal to the circuits encl...

System identification
The field of system identification uses statistical methods to build mathematical models of dynamical systems from measured data. System identification also includes the optimal design of experiments...
Nonlinear control
Nonlinear control theory is the area of control theory which deals with systems that are nonlinear, time-variant, or both. Control theory is an interdisciplinary branch of engineering and mathematics...

People in systems and control
This is an alphabetical list of people who have made significant contributions in the fields of system analysis and control theory.
Control engineering
Control engineering or control systems engineering is the engineering discipline that applies control theory to design systems with desired behaviors. The practice uses sensors to measure the output ...
Decision theory
Decision theory or theory of choice in economics, psychology, philosophy, mathematics, computer science, and statistics is concerned with identifying the values, uncertainties and other issues relevan...
Estimation theory
Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured/empirical data that has a random component. The parameters describe an underlying phy...
Filter design
Filter design is the process of designing a signal processing filter that satisfies a set of requirements, some of which are contradictory. The purpose is to find a realization of the filter that mee...
Motion control
Motion control is a sub-field of automation, in which the position or velocity of machines are controlled using some type of device such as a hydraulic pump, linear actuator, or electric motor, genera...
Optimal control
Optimal control theory, an extension of the calculus of variations, is a mathematical optimization method for deriving control policies. The method is largely due to the work of Lev Pontryagin and his...
