“How can we use synchronous motors to stabilize the grid?”
Synchronous Motors are great for precision control applications. But their usage can be applied to grid stabilizations. Since voltage in a grid can fluctuate, by running synchronous motors at no-load speeds we can effectively have a load that adds inertia to the system, therefore mellowing out the voltage fluctuation. These devices are known as a Synchronous Compensators and are a vital part of the modern grid.
“How can we measure the acceleration of an object?”
Acceleration can be one of the most important things for an engineer to measure. But we will need a tool to accomplish this. This is how we can use accelerometers, which measure the stresses on piezoelectric material to determine acceleration.
Extremum Seeking Control
“Is there a control method that tries to sets a function at its extreme value?”
Control Theory is a deep subject. There seems to be a control method for every situation. And one of those situations might happen to be one where people are trying to keep a function at its extremum (the maximum or minimum absolute value). This Extremum Seeking Control allows for this to happen, and also gives it the privilege of heightened sensitivity reduction and disturbance rejection.
“How can we measure how long it takes for an energy generator to come online?”
Things in the physical world tend to have inertia. Electricity generating sources are no different. As a result, they will have a ramp rate in kW/minute that measures how long they take to come online.
“What makes autonomous vehicles work?”
Autonomous vehicles, archeological scanning, soil imaging, and automated agriculture all rely on knowing real-time distance to work. However, how exactly can we accomplish this? Well, let’s use our engineering mindset to find out. We know that if we send a beam of light from a laser somewhere, then it can be reflected back. And since the speed of light is constant in a uniform medium, if we measure the time it took to return, we can obtain a measurement for distance. This system is known as LIDAR Scanning, which stands for Light Detection and Ranging. LIDAR has caused a revolution in multiple fields of science and is moving every day closer and closer to mainstream adoption.
“How can we control processes?”
Industrial processes are at the heart of the industrial internet of things. However, in order to ensure that the process is going in accordance with the procedure, there must be some form of guidance. For that reason, engineers have developed something known as Process Control, which allows a systems process to stay within all setpoints.
Inkjet Solar Cell
“How can we print solar cells?”
To secure energy independence and security, solar cells need to be manufactured at an incredible rate. Part of this includes an initiative to print solar cells known as inkjet solar cells. This will allow for an exponential increase in the number of usable solar, and can result in a massive energy transition.
