A thermodynamic equilibrium prediction is firstly performed to obtain an optimal working condition at temperature of 750degC and at mole flow rate ratio of ethanol to water of 1:3. The mass flow rates of ethanol and water are then controlled to meet the requirement of hydrogen production at 30SLPM. Finally, with energy balance equation, the temperature control is designed using electric power to maintain the thermal plasma reformer at working temperature of 750degC and desired inlet mass flow rate of fuel and water. Both mass flow rate and temperature controls are implemented in an electric control unit with a PID control law. The experimental data, which are collected from the 1 kWe thermal plasma reformer at Clean Energy R&D Center, Da-Yeh University, Taiwan, R.O.C., are compared with the predicted data. The results show that they approximately fit in with each other at temperature of 750degC under the ethanol/water mole flow rate of 1:3.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125888731","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}

The problem of decoupling the roll response and the sideslip response using model-matching approach is considered along with control sensitivity minimization. In contrast to the conventional two degree of freedom controller design using model-matching approach, a single degree of freedom controller is designed in this paper for ease of implementation. Gain scheduling is avoided by designing the controller at a single flight condition that robustly stabilizes the closed loop system and retains performance characteristics at all flight conditions. For the purpose of determining the design point, two approaches, namely worst-case analysis and proximity of plant models is performed at all flight conditions. Robustness of the closed loop system to both structured and unstructured uncertainties at all flight conditions is examined through mu analysis. Final flight test results are compared with offline nonlinear simulations.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130851637","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}

On the basis of a nonlinear model of a wind turbine, a set of operating conditions is identified and a LQ controller is designed for each operating point. The controller gains are then interpolated linearly to get a control law for the entire operating envelope. The states and the gain-scheduling variable are not online available and an observer is designed. This is done in a modular approach in which a linear estimator is used to estimate the non-measured state variables and the unknown input, aerodynamic torque. From the estimated aerodynamic torque and rotor speed and measured pitch angle the scheduling variable effective wind speed is calculated by inverting the aerodynamic model. Simulation results are given that display good performance of the observers and comparisons with a controller designed by classical methods display the potential of the method.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"32 24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125737298","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}

Hybrid systems combine continuous and discrete (event-based) dynamics, which is exactly the case in an inverter-driven BLDCM. The model presented in this work consists of a general automaton with discrete states, combined with a set of continuous dynamic equations describing the electro-mechanical behavior of the motor. One of the significant benefits of this strategy is that the model describes the motor under all possible operating conditions. The model is derived for the common case of a BLDCM in wye-connection with a three-leg inverter. The model is verified on a real BLDCM drive and shows good agreement with experiments.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124156597","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}

To isolate and estimate the possible actuator faults, we first relate each possibility to a faulty model, then for each possible faulty model, we design a corresponding sliding mode observer (SMO), the residuals are defined as the norm of the magnitudes of the output estimation errors resulting from all possible faulty models. It is proved that, for the faulty model corresponding to the faulty actuator, the designed SMO can ensure the related output estimation error converges to a sufficiently small neighborhood. It is also shown that, for all other possible faulty models, the related output estimation errors are much larger.

After reviewing proportional-integral-derivative (PID) control, we analyze RMS level-tracking controllers, which induce a stable limit cycle with specified RMS level when an audio effect is placed in the feedback loop. The space of the RMS level-tracking controllers whose error converges exponentially to zero is succinctly described, and this space is augmented to include controllers that support multiple stable equilibria. Next, an adaptive RMS level-tracking controller is developed that can accommodate changing instrument and audio effect parameters. Finally, several example controllers are tested on a simulated vibrating string to demonstrate 1) creating multiple stable equilibria, 2) driving amplitudes of the string harmonics to various targets (for instance to make the string \"sing\" vowels), and 3) reducing the dynamic range of resonant ring modulation for time-varying effect parameters.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131266950","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}
