PhD Candidate and Control Systems Engineer
Bogac Canbaz
I am a PhD candidate in Electrical Engineering at the University of Nebraska-Lincoln, graduating in December 2026. I design optimal and nonlinear control algorithms from first principles and prove them on hardware under hard real-time constraints.
What I do
I design feedback control systems for complex electromechanical machines: multibody systems whose dynamics are nonlinear, whose axes are coupled to one another, and whose behavior changes with configuration, load, and wear. These are the systems where a linear controller tuned at one operating point quietly stops being valid at another, and where the honest answer to whether a design works can only come from the hardware.
My dissertation built the first real-time control stack reported in the literature for an underactuated gyroscopic system, a machine with fewer actuators than degrees of freedom and a singular configuration it must never reach. My first design passed every check in simulation and then failed on the rig, close to that singularity. Rebuilding it as a constrained nonlinear controller, one that carries the limit inside the control law rather than assuming the plant will stay away from it, produced a system that settles faster, tracks more accurately, and holds the machine inside its safe envelope throughout.
I work across the whole path: deriving the dynamics, formulating the cost and constraint terms, deploying generated code onto real-time targets, and defining the gates a controller has to clear before it is allowed anywhere near the hardware. I am drawn to complex electromechanical systems, where controls is the layer that turns planned intent into motion that is precise, smooth, and safe.
The problems I want to work on sit at that boundary. How do you control a machine that has fewer actuators than degrees of freedom, so that some axes can only be moved indirectly through the coupling? How do you keep a system inside its safe operating envelope when the constraint is not a soft preference but a configuration the machine must never reach? How do you build a controller that stays stable when the friction, the payload, and the disturbances are unknown and changing, without retuning it for every case? How do you recover the states you need from the sensors you actually have, rather than the ones the model assumed?
What I work on
- Modeling and simulation of electromechanical systems
- Deriving multibody dynamics from first principles, building plant and controller models in MATLAB/Simulink, and multiphysics finite element analysis in COMSOL and ANSYS where thermal, structural, and electrical behavior are coupled.
- Nonlinear and robust control design
- Sliding mode and adaptive control, optimal state feedback, cascaded loops, and active disturbance rejection, with stability established through Lyapunov analysis rather than assumed from simulation results. I am particularly drawn to underactuated systems, where there are fewer actuators than degrees of freedom and the usual design shortcuts stop working.
- State estimation and sensor fusion
- Observer design, filtering, and fusing position, current, and inertial measurements into the state a controller needs, including physics-informed learned estimators constrained by the governing equations of the plant.
- Design optimization under real constraints
- Searching a design space against the limits that actually bind: stress, thermal margin, actuator saturation, parasitics, manufacturability. A design that only works on paper has not been optimized, it has been sketched.
- Real-time implementation and hardware validation
- Deploying control loops on resource-constrained real-time targets, instrumenting a test rig, and running the experiments that decide whether the design was right. Most of what I know about control I learned from the gap between what the simulation predicted and what the hardware did.
Where it applies
The mathematics of underactuated, strongly coupled multibody control is not specific to one industry. The same structure appears wherever a machine has to move precisely without a rigid reference to push against. These are the areas I find most compelling.
- Robotic manipulators and mobile robots. Serial arms with configuration-dependent inertia, compliant and flexible joints, and contact tasks where the controller has to stay stable through changing dynamics.
- Attitude control and stabilization platforms. Momentum-exchange actuators for spacecraft and satellites, and the gyroscopic stabilizers used on ships, camera platforms, and self-balancing vehicles.
- Aerial and unmanned vehicles. Guidance, navigation, and control for systems with no stationary frame, where attitude is regulated through coupling between rotating bodies and control surfaces.
- Marine and underwater vehicles. Orientation control under buoyancy, added mass, and wave-induced disturbances the controller never measures directly.
- Industrial automation and motion control. High-speed multi-axis actuators, smooth trajectory generation with bounded jerk, and protective logic that keeps a machine inside its safe envelope.
- Power electronics and drives. Motor drive and inverter design, and translating electrical and thermal limits into control constraints so the hardware is never asked for more than it can survive.
