ABS control - A design model and control structure
- 2003

Ingår i: Nonlinear and Hybrid Systems in Automotive Control. ; , s. 85-96

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The Anti-lock Braking System is an important component of acomplex steering system for the modern car. Most of ABS controllersavailable on the market are table and relay-feedback based.In the latest generation of “brake by wire” systems, the performancerequirements on the ABS are much higher. Control objective shiftsto maintain a specified tire slip during braking. The authors propose a design model and based on that a gain-scheduled controller that regulates the tire-slip. Simulation and test results are presented.

Hybrid control techniques for switched-mode DC-DC converters part I : The step-down topology
- 2007
-
Ingår i: 2007 American Control Conference. - : IEEE. - 1424409888 - 9781424409884 ; , s. 5450-5457
-
Konferensbidrag (refereegranskat)abstract
- Several recent techniques from hybrid and optimal control are evaluated on a power electronics benchmark problem. The benchmark involves a number of practically interesting operating scenarios for a fixed-frequency synchronous step-down dc-dc converter. The specifications are defined such that good performance only can be obtained if the switched and nonlinear nature of the problem is respected during the design phase.

Distributed Robustness Analysis of Heterogeneous Networks Via Integral Quadratic Constraints
- 2015
-
Ingår i: American Control Conference, 2015.
-
Konferensbidrag (refereegranskat)abstract
- Robust performance of networks of interconnected heterogenous nonlinear dynamic systems is studied using the theory of integral quadratic constraints. By appealing to recent results on chordal sparsity decompositions of rational transfer matrices, distributed and scalable certificates for performance of interconnections are proposed. The approach is more direct since it does not involve reformulating the problem in terms of standard closed-loop configurations as is typical in the literature, which may destroy or conceal the structural properties inherent in the interconnections. The well-studied notion of feedback performance is reinvestigated within this framework. It is shown that feedback performance can be verified in a distributed fashion if the signal variables in the feedback interconnection are selected appropriately. Another contribution of the paper lies in identifying three chordality-preserving operations that are standard in control and modelling theory, namely local feedback, feedforward, and additive input-output perturbations.

Robust Feedback Stability of Negative Imaginary Systems: An Integral Quadratic Constraint Approach
- 2015
-
Ingår i: 2015 European Control Conference (ECC). - 9783952426937
-
Konferensbidrag (refereegranskat)abstract
- Sufficient conditions for stability of feedback interconnections of negative imaginary systems are derived via an integral quadratic constraint (IQC) approach. These extend existing results in the literature by exploiting the flexibility present at the static and infinite frequencies to reduce conservatism. Negative imaginary transfer functions with poles on the imaginary axis are accommodated using a recently generalised IQC-based robustness result. In particular, the negative imaginary property of systems is shown to give rise to IQCs on positive frequencies that are bounded away from zero and infinity. Additional quadratic conditions are introduced to take care of the IQCs near the DC and instantaneous gains of the systems.
