The second purpose is to apply the proposed method to estimate the Hungarian potential GDP in 2000–2021. The novelty of the proposed filter method is that — unlike papers published so far — it does not require the stability of the dynamic model, only a partial stability condition must be satisfied. Moreover, such time-dependent uncertainties and nonlinearities can arise in the model that satisfy a general quadratic constraint. An important advantage of the proposed robust filter method over the traditional Kalman filter is that no stochastic assumptions is needed that may not be valid for the problem at hand. The proposed filter method has never been applied to estimate the potential GDP. To estimate the Hungarian potential GDP, the proposed method is applied using uni-, bi- and trivariate models. Estimations up to 2021 has not been published yet for the Hungarian economy. The examined period includes both the financial world crisis and the Covid-19 crisis. The results of the different models are consistent. It turned out that the economic policy was very procyclical after 2012, and the GDP gap was still positive during and also after the Covid-19 crisis.}, year = {2023}, eissn = {1613-9178}, pages = {1183-1207} } @article{MTMT:32473873, title = {Robust energy-to-peak filter design for a class of unstable polytopic systems with a macroeconomic application}, url = {https://m2.mtmt.hu/api/publication/32473873}, author = {Gyurkovics, Éva and Takács, Tibor}, doi = {10.1016/j.amc.2021.126729}, journal-iso = {APPL MATH COMPUT}, journal = {APPLIED MATHEMATICS AND COMPUTATION}, volume = {420}, unique-id = {32473873}, issn = {0096-3003}, year = {2022}, eissn = {1873-5649} } @article{MTMT:31184154, title = {Dynamic output feedback H ∞ design in finite-frequency domain for constrained linear systems}, url = {https://m2.mtmt.hu/api/publication/31184154}, author = {Kazemy, Ali and Gyurkovics, Éva and Takács, Tibor}, doi = {10.1016/j.isatra.2019.06.005}, journal-iso = {ISA T}, journal = {ISA TRANSACTIONS}, volume = {96}, unique-id = {31184154}, issn = {0019-0578}, year = {2020}, eissn = {1879-2022}, pages = {185-194} } @article{MTMT:31147152, title = {LMI approach to global stability analysis of stochastic delayed Lotka–Volterra models}, url = {https://m2.mtmt.hu/api/publication/31147152}, author = {Kiss, Krisztina and Gyurkovics, Éva}, doi = {10.1016/j.aml.2020.106227}, journal-iso = {APPL MATH LETT}, journal = {APPLIED MATHEMATICS LETTERS}, volume = {104}, unique-id = {31147152}, issn = {0893-9659}, year = {2020}, eissn = {1873-5452}, orcid-numbers = {Gyurkovics, Éva/0000-0003-2355-4113} } @article{MTMT:30702684, title = {Sliding mode synchronization of a delayed complex dynamical network in the presence of uncertainties and external disturbances}, url = {https://m2.mtmt.hu/api/publication/30702684}, author = {Kazemy, A. and Gyurkovics, Éva}, doi = {10.1177/0142331218805533}, journal-iso = {T I MEAS CONTROL}, journal = {TRANSACTIONS OF THE INSTITUTE OF MEASUREMENT AND CONTROL}, volume = {41}, unique-id = {30702684}, issn = {0142-3312}, year = {2019}, eissn = {1477-0369}, pages = {2623-2636} } @article{MTMT:30330795, title = {Comparison of some bounding inequalities applied in stability analysis of time-delay systems}, url = {https://m2.mtmt.hu/api/publication/30330795}, author = {Gyurkovics, Éva and Takács, Tibor}, doi = {10.1016/j.sysconle.2018.10.017}, journal-iso = {SYST CONTROL LETT}, journal = {SYSTEMS & CONTROL LETTERS}, volume = {123}, unique-id = {30330795}, issn = {0167-6911}, year = {2019}, eissn = {1872-7956}, pages = {40-46} } @article{MTMT:30309979, title = {Non-fragile exponential synchronization of delayed complex dynamical networks with transmission delay via sampled-data control}, url = {https://m2.mtmt.hu/api/publication/30309979}, author = {Gyurkovics, Éva and Kiss, Krisztina and Kazemy, Ali}, doi = {10.1016/j.jfranklin.2018.10.005}, journal-iso = {J FRANKLIN I}, journal = {JOURNAL OF THE FRANKLIN INSTITUTE-ENGINEERING AND APPLIED MATHEMATICS}, volume = {355}, unique-id = {30309979}, issn = {0016-0032}, year = {2018}, eissn = {1879-2693}, pages = {8934-8956}, orcid-numbers = {Gyurkovics, Éva/0000-0003-2355-4113} } @misc{MTMT:3347654, title = {A note on relationship between some bounding inequalities in stability analysis of time-delay systems}, url = {https://m2.mtmt.hu/api/publication/3347654}, author = {Gyurkovics, Éva and Takács, Tibor}, unique-id = {3347654}, year = {2017} } @article{MTMT:3225264, title = {Stability analysis of linear systems with interval time-varying delays utilizing multiple integral inequalities}, url = {https://m2.mtmt.hu/api/publication/3225264}, author = {Gyurkovics, Éva and Szabó-Varga, Gabriella and Kiss, Krisztina}, doi = {10.1016/j.amc.2017.05.004}, journal-iso = {APPL MATH COMPUT}, journal = {APPLIED MATHEMATICS AND COMPUTATION}, volume = {311}, unique-id = {3225264}, issn = {0096-3003}, year = {2017}, eissn = {1873-5649}, pages = {164-177} } @article{MTMT:3034032, title = {Multiple summation inequalities and their application to stability analysis of discrete-time delay systems}, url = {https://m2.mtmt.hu/api/publication/3034032}, author = {Gyurkovics, Éva and Kiss, Krisztina and Nagy, Ilona and Takács, Tibor}, doi = {10.1016/j.jfranklin.2016.10.006}, journal-iso = {J FRANKLIN I}, journal = {JOURNAL OF THE FRANKLIN INSTITUTE-ENGINEERING AND APPLIED MATHEMATICS}, volume = {354}, unique-id = {3034032}, issn = {0016-0032}, year = {2017}, eissn = {1879-2693}, pages = {123-144} }
