This control system design, based on decomposition and Freund's nonlinear decoupling control theory with arbitrary pole placement, decouples the motor-robot configuration into robot, motor, and series compliance (interaction) subsystems. This approach is in contrast to the conventional treatment of the motor as a pure torque source and the neglect of dynamic interactions between the robot joint and the motor drive mechanism.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":"18 1","pages":"1333-1338"},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73843848","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}

A simple model representative of the aerospace plane concept, including a dual-mode propulsion system composed of SCRAMJET and rocket engines, is presented. Consideration is restricted to hypersonic flight within the atmosphere. An energy state approximation is employed in a four-state model for flight of a point mass in a vertical plane. Trajectory constraints, including those of dynamic pressure and aerodynamic heating, are initially ignored. Singular perturbation methods are applied in solving the optimal control problem of minimum fuel climb. The resulting reduced solution for the energy state dynamics provides an optimal altitude profil1e dependent on energy level and control for rocket thrust. A boundary-layer analysis produces an approximate lift control solution in feedback form and accounts for altitude and flight path angle dynamics. The reduced solution optimal climb path is presented for the unconstrained case and the case for which a maximum dynamic pressure constraint is enforced.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":"14 1","pages":"1406-1411"},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73890831","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}

Though curent control system design techniques may be adequate to handle the range of flight conditions and maneuvers demanded, further compensation for system malfunctions and/or battle damage has heretofore been extremely difficult - unless one has accepted significant performance penalties at each operating point to obtain a very conservative control solution that can deal with awide range of potential impairments. What is needed is a method for developing simple, robust, high-performance control systems that vary in real time with operating and fault condition changes in the system being controlled; that is, that \"reconfigure\" rapidly to face rapidly changing conditions. The \"super-controller\" strategy, outlined here, shows promise of meeting this need. This paper describes the super-controller design technique and preliminary simulation results based upon single and multiple simultaneous effector impairments of a control reconfigurable combat aircraft (CRCA).","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":"40 1","pages":"2225-2231"},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75880094","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 is shown that the zeros of a polytope P of n-th order real polynomials is contained in a simply connected region D if and only if the zeros of all polynomial along the exposed edges of P are contained in D. This paper is motivated by the fact that the requirement of simple connectedness of D may be too restrictive in applications such as dominant pole assignment and filter design where the separation of zeros is required. In this paper, we extend the \"edge criterion\" in [2] to handle any region D whose complement Dc has the following property: Every point d Dc lies on some continuous path which remains within Dc and is unbounded. This requirement is typically verified by inspection and allows for a large class of disconnected regions. We also allow for polynomials with complex coefficients.","PeriodicalId":6395,"journal":{"name":"1988 American Control Conference","volume":"22 1","pages":"2461-2464"},"PeriodicalIF":0.0,"publicationDate":"1988-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76575396","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}
