“What is one possible way to speed up EV recharge times?”

 

In order to achieve deep-decarbonization of transportation, the global vehicle fleet needs to become much more electrified. However, the long recharge times associated with electric vehicles are a roadblock for this to happen. One way to solve this would be to implement Ultracapacitors for EVs. Ultracapacitors have quick recharge times, low weight, and low degradation, making them a formidable option. The downside is that manny ultracapacitors lack the storage capacity found in traditional solid-state batteries. But if this problem gets solved, then expect a paradigm shift in the EV industry!

“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.

“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.

“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.
