Control of Active Suspensions With Pump-Controlled Electro-Hydraulic Actuators / Finite-time Estimation for Time Varying Systems with Delay
Abstracts:
Control of Active Suspensions With Pump-Controlled Electro-Hydraulic Actuators Under Uncertainties and Constraints Using Adaptive Dynamic Programming
This talk introduces about a novel control design for an active quarter-car suspension with pump-controlled electrohydraulic actuator (EHA) requiring only limited information about the pump-controlled EHA and considering constraints. The control design consists of two parts: force reference generation and force tracking. The force reference is determined with a novel off-policy adaptive dynamic programming (ADP) algorithm ensuring constraint satisfaction. The force tracking is achieved by means of an adaptive robust control (ARC) framework. Closed-loop stability is investigated. The effectiveness of proposed control design is validated by simulations.
Finite-time Estimation for Time Varying Systems with Delay
Constructing asymptotic observers for engineering systems is an important topic that is motivated by the difficulty of measuring state variables of systems. However, less attention has been paid to constructing finite-time observers, whose objective is to find values for states of the system after a predetermined finite time. Such a problem is important in engineering processes with deadlines and solving it can make it possible to design output feedback stabilizing controls. Moreover, measurement delays are present in many practical applications, such as chemical processes, aerodynamics, and communication networks, and they are time-varying. Therefore, the problem of finite-time estimation of systems with a time-varying delay is strongly motivated. The main aim of this talk is to present the design of finite-time observers for time-varying systems in the presence of a time-varying delay.

The seminar takes place at the ITWM every 1st Tuesday of a month (besides holidays and summer break). Aims are broadening of experiences and exchange of scientific views – also beyond the organizing groups.
Typical subjects of talks are:
- ongoing or recently finished graduations and doctoral theses
- current research and projects
The topics vary from mathematical methods to technical implementations. Usually, the talks present research results. However, some show open issues for brainstorming and inputs from the audience.
