Both cases of time-invariant and time-varying uncertain probability with an upper bound are considered by introducing different classes of parameter-dependent Lyapunov functions. For time-invariant uncertain packet-loss probability, a new necessary and sufficient condition which can be solved by LMIs is proposed for the mean-square stability, and the largest upper bound of the packet-loss probability can be therefore obtained. For time-varying uncertain packet-loss probability, a sufficient condition in the form of LMIs is derived. Moreover, the proposed methodologies are further developed for the case where there are multiple packet-loss channels with respective uncertain probability under the parallel transmission strategy.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129658776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our prototypical class of systems is conformed by kinematic models of non-holonomic systems such as the unicycle or a car with N trailers. We restrict our class of inputs to those which are piecewise constant. The restriction gives way to an easy implementation in discrete time and allows to formulate control problems as systems of polynomial equations. The control problems can then be addressed using geometric-algebraic tools and can be solved explicitly using symbolic computational software if their size is reasonable.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131389896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of its simple tuning procedure and good set-point tracking capabilities, Internal Model Control (IMC) has established good results for these processes. However, disturbance rejection is an important issue in process control, especially in delayed systems. The basic tuning rules for IMC exhibits rather sluggish disturbance rejection performance, especially for delay dominant processes (i.e. the relative delay to the process time constant). In this paper we propose a special tuning for effective disturbance rejection with IMC. The proposed disturbance filter compensates nicely for the dead-time, when stochastic disturbance signals have their main spectral energy in a limited frequency interval. The tuning method is using the Diophantine equations to determine the disturbance filter coefficients. Simulation results demonstrate the effectiveness of the proposed approach, as well as its intrinsic robustness when compared to the basic IMC tuning.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124436563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simultaneous Model Order and Parameter Estimation (SMOPE) has been proposed to address system identification problem efficiently using optimization algorithms. The technique enables the computation of model order and parameters values to be done concurrently. The performance of SMOPE has been tested using particle swarm optimization (PSO) and gravitational search algorithm. However, the performance was worse than conventional ARX method. Current optimum opposition-based simulated Kalman filter (COOBSKF) is an improved version of simulated Kalman filter (SKF) which employs the concept of current optimum opposition-based learning (COOBL). Therefore, the objective of this paper is to test the effectiveness of the COOBSKF in solving system identification problem throughout SMOPE. Experiments are conducted on six system identification problems. The obtained outcomes showed that the performance of the SMOPE using COOBSKF is better than other SMOPE-based approaches.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117266295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At several steady points, local linear statespace models with input and output offsets are identified by a subspace identification method. We propose a state-space unification method of the identified local linear models, where an affine transformation is introduced for each pair of adjacent local systems. The affine transformations are chosen by using similarities of the system expressions. The matrices and offsets of the affine transformations are uniquely calculated by the least-squares method. Our method considers the change of steady points by the offset terms in the affine transformations. By the transformations, a linear parameter-varying system model with bias terms is obtained. The parameter is determined by the value of the unified state, and therefore we can finally obtain a nonlinear dynamical model, which is valid around the equilibria set. A numerical simulation is shown for confirming an availability of this method.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130089322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While both controllers ensured that the 3200 kg elevator car reached the top floor within the required time of 65 s, it was clear that the pseudo-derivative feedback controller exhibited better performance.

However, disturbances like solar irradiation or deterioration of the heat transfer coefficient α of the ICB are typically not detected by sensors. In this paper a disturbance observer for solar irradiation is used to design a fast sampled disturbance compensation obtaining a fast response of the system. Two specific characteristics of the disturbance are utilized to estimate α: 1) During nighttime solar irradiation has its minimum. 2) α declines at a very slow rate. The MPC, irradiation estimation, and α estimation are implemented with different sampling rates. This enables separate and robust estimation and efficient implementation. The system and control architecture is presented, the concept of the observer and estimation is given and simulation results demonstrate the performance of the concept.","PeriodicalId":122301,"journal":{"name":"2018 SICE International Symposium on Control Systems (SICE ISCS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114714236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
