Hydraulic Actuated Rear Wing system

Hi, I am currently working on a project at Uni that involves coming up with an ECS for an adaptive rear wing system. I plan on using hydraulics due to their fast response time, I want to set up a pump attached to two accumulators which in turn are each connected to a solenoid valve and the linear hydraulic actuator at the start of one accumulator will be empty and the actuators top chamber full when the wing is required to tilt the full accumulator will empty into the bottom chamber forcing the fluid in the upper chamber back into the empty accumulator beginning a cycle in which the fluid is forced into accumulators from the actuator conserving energy. excess fluid from filling the actuator is rerouted with the solenoid valve to the pump where it is routed using a solenoid valve to whichever accumulator will be filled next cycle.

Will This concept work and what are things I should tweak?

OK, so what's their design requirement? Are they really building a control system to deal with 0.2 second actuation, which would require something like a 250-Hz control bandwidth?
 
This really depends on HOW you think your control system is even going to know WHEN it's cornering. You can't depend on braking alone, since there are other times you might be braking, and it might be disastrous if you suddenly deployed air braking while you were maneuvering for an advantage.

I would guess that it would if you have a high performance inertial navigation system, you might get an answer in under 0.5 seconds; may be less if it's augmented with a detailed mapping system
You're absolutely right. Braking alone can't be relied upon as a signal for cornering, since braking happens in other situations too, and suddenly deploying air brakes while maneuvering could definitely be dangerous.


If you have a high-performance inertial navigation system and accurate mapping data, detecting cornering could definitely happen in under 0.5 seconds, as you mentioned. However, another important aspect might be the decision-making process of the system. Using predictive algorithms or machine learning could help the system anticipate upcoming maneuvers, which would improve its ability to detect cornering and optimize response times
