Nonlinear control of actuator
APPLICATION FOR AUTOMOTIVE THROTTLE
Due its important friction and specific return spring, the automotive throttle represents strongly nonlinear system difficult to control in desired quality. Typically, the so-called composite regulator is used, where a conventional PID is supplied with nonlinear feedback or feedforward compensators. We published the results in the field of designing the new arrangement of a regulator and in the field of application of approximation methods with the use of local linear models.

Rapid Control Prototyping and HIL
WE DEVELOP AND APLY SOLUTIONS OF SPECIFIC PROBLEMS IN MECHATRONICS
Within the frame of 7RP ESPOSA project, we work with HIL simulations of chosen components and we prepare the environment for C-code automatic generating from Simulink meeting the criteria for the certification according to the DO-178b and MISRA standards.

Experimental 4WD/4WS Vehicle
ALGORITHMS FOR ESTIMATING THE VEHICLE STATE, DRIVING DYNAMICS MODELS
The aim of the Car4 project is the construction of an experimental vehicle for the purposes of development and testing the algorithms of driving stability and comfort, focused mainly on personal vehicles. All the wheels of the Car4 are independently driven and controlled, which enables to evaluate and to test the advanced algorithms of the driving stability and traction. The vehicle manoeuvrability is enhanced in comparison with the more common concept with one axle driven as a whole. Another aim is to support the students´ teamwork and their motivation for independent work within particular tasks, in the sense of mechatronic methods.
