Engineering Application I
Control strategy development for supersonic blowdown wind tunnel
Facility in the areo-lab:
Target
- Regulate the gas pressure in the test section to the setpoint
- Maximize the usage of the compressed air the storage tank and exted the test time as much as possible
Challegening issues
- Nonlinearity in the state variation of gas
- Uncertainty in the control valve characteristics
- Sensor noises
Engineering Application II
Development of power management strategy for electric vehicle
Schematic of an EV:
Target
Maximize the energy stored in the batteries and auxilliary elements to extend the driving range as much as possible
Challenging issues
- Dynamic characteristics of motors
- Charging and discharging profile of batteries
- Control implementation in DC/DC
