In this research, control techniques not needing a mathematical model of the system are subject to study. Neuro-predictive (NP) method is a non-model based technique works for a wide variety of nonlinear systems, and lets us compare different systemspsila behaviour. In this paper, two different nonlinear systems, a model helicopter and a tank reactor, are controlled similarly by neuro-predictive method in simulation environment. Although tank reactor is controlled successfully by NP method, a repeated significant overshoot is observed when model helicopter is controlled (leading very long settling time and a considerable amount of energy consumption). This discrepancy in control behaviour is explained by a property of systems, called ldquocontrol inertiardquo. In this paper, control inertia is defined as the ratio of control input to the second temporal derivative of systempsilas output. It is indicated that the undesirable control behaviour of model helicopter (repeated overshoot and its consequences) is influenced by its high control inertia. In order to improve the control behaviour, a fuzzy inference system is designed and added to the control circuit to decelerate system when it is approaching setpoint. This fuzzy inference system is called ldquofuzzy brakerdquo, which improves the performance significantly in case of high inertia. Having a general understanding of systempsilas dynamics (not necessarily a mathematical model), it is possible to judge whether the system is high inertia or low inertia, and whether a fuzzy brake is needed or not. In general, the concept of control inertia can be used in intelligent control system design together with input-output data and fuzzy rules derived by experience/observation.","PeriodicalId":350202,"journal":{"name":"2008 5th International Symposium on Mechatronics and Its Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122772285","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}

In this paper a recursive Lyapunov function is introduced to ensure the stability around a fixed set-point using backstepping control algorithm. The BFL controller utilizes the advantage of fuzzy logic to schedule the backstepping controller parameters. This resulted in improved performance compeered with that achieved by backstepping controller alone. On the other hand, the BLMS controller is used to minimize the control efforts by finding the parameters of backstepping controller which provide minimum control efforts to the system. Finally, a comparison between Backstepping, BFL and BLMS controllers are presented. BLMS controller suffered from a slow time response while having reduced control effort when compared with the BFL controller. Combined performance of the BFL controller was superior to the backstepping or BLMS controller.","PeriodicalId":350202,"journal":{"name":"2008 5th International Symposium on Mechatronics and Its Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128385239","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}

It focuses on adaptive gas-spring-dampers (GSD) for passenger cars and, particularly, a novel valve for this unit. Gas-springs for passenger cars became more popular over the last fifteen years. Its main advantage is the payload-independent eigenfrequency of the body. This independency is due to a proportional increase of spring rate and spring force. However, for any given damper rate the resonance magnification rises with the payload leading to discomfort and non-optimal driving safety. An adaptive damper suppresses this dependency. The GSD comprises two chambers with compressed gas connected by a mechatronic valve modulating the air flow between those. The valve comprises a piezo ring shored up by spokes from an inner bearing. When the piezo ring is contracted, it rotates due to the (3,1)-piezoelectric effect. This rotation modulates the valve crossing section and hence controls the air flow. The actuator design involves the specification the kinematic structure as well as raw geometric data like actuator force and motion. Here, the synthetic kinematic structures, which are based on structured piezo ceramics, are tense integrity closed. A fine tuning of geometric and material parameters is performed in an iterative process.","PeriodicalId":350202,"journal":{"name":"2008 5th International Symposium on Mechatronics and Its Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130369294","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}
