One procedure for retaining uniform handling qualities over such an envelope is to implement a digital adaptive controller. Towards such an implementation an explicit adaptive controller which makes direct use of online parameter identification, has been developed and applied to both linearized and nonlinear equations of motion for a typical fighter aircraft. This controller is composed of an online weighted least squares parameter identifier, a Kalman state filter, and a model following control law designed using single stage performance indices. Simulation experiments with realistic measurement noise indicate that the proposed adaptive system has the potential for on-board implementation.","PeriodicalId":164707,"journal":{"name":"1975 IEEE Conference on Decision and Control including the 14th Symposium on Adaptive Processes","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125804453","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}

Compensators for state feedback control laws which satisfy the algebraic separation principle 满足代数分离原理的状态反馈控制律补偿器

{"title":"Compensators for state feedback control laws which satisfy the algebraic separation principle","authors":"G. Grubel","doi":"10.1109/CDC.1975.270619","DOIUrl":"https://doi.org/10.1109/CDC.1975.270619","url":null,"abstract":"A synthesis procedure for dynamic compensators based on a differential operator representation is developed. The compensators satisfy the algebraic separation, principle and may qualify as 'control observers'. As such they show the same properties as a state observer in a control loop. However, this compensator approach is more general, in that it immediately allows zero placement to be taken into account. For single-input, multi-output systems, a simple and unified procedure, for the construction of minimal order compensators with and without arbitrary pole placement is established. This procedure then is generalized in a straightforward way to the construction of low order compensators for multi-input systems. The approach is particularly advantageous if a higher order (dynamic) state feedback control law is given. In this case, a total compensator of minimal order can be constructed.","PeriodicalId":164707,"journal":{"name":"1975 IEEE Conference on Decision and Control including the 14th Symposium on Adaptive Processes","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123784654","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 unifying approach to linear estimation via the partitioned algorithms, I: Continuous models 一个统一的方法,线性估计通过分割算法,I:连续模型

{"title":"A unifying approach to linear estimation via the partitioned algorithms, I: Continuous models","authors":"D. Lainiotis, K. Govindaraj","doi":"10.1109/CDC.1975.270586","DOIUrl":"https://doi.org/10.1109/CDC.1975.270586","url":null,"abstract":"In this paper, the fundamental nature of the \"partitioned\" algorithms is demonstrated by showing that the \"partitioned\" algorithms serve as the basis of a unifying approach to linear filtering and smoothing. Specifically, generalized \"partitioned\" filtering and smoothing algorithms are given in terms of forward and backward-time differentiations that are theoretically interesting, possibly computationally attractive, as well as provide a unification of the previous major approaches to filtering and smoothing and clear delineation of their inter-relationships. In particular, the generalized \"partitioned\" filtering algorithms are shown to contain as special cases both the Kalman-Bucy filter as well as the Chandrasekhar algorithms. Furthermore, the generalized \"partitioned\" algorithms lead to important generalizations of the Chandrasekhar algorithms [5-7, 18- 19], as well as of the previous \"partitioned\" algorithms of the author [15-19]. These generalizations pertain to arbitrary initial conditions and time-varying models. It is also shown [20-22] that the generalized \"partitioned\" algorithm may also be given in terms of an imbedded generalized Chandrasekhar algorithm with the consequent possible computational advantages. Similarly, the generalized \"partitioned\" smoothing algorithm is shown to contain as special cases the major algorithms for smoothing such as those of Mayne and Fraser [9-10], Kailath and Frost [12], and Meditch [11], as well as the related ones of Zachrisson [13], and Biswas and Mahalanobis [14]. Finally, backwards smoothing algorithms for arbitrary boundary conditions are also obtained as a special case of the \"partitioned\" smoothing algorithms.","PeriodicalId":164707,"journal":{"name":"1975 IEEE Conference on Decision and Control including the 14th Symposium on Adaptive Processes","volume":"38 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126951104","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 minimum fuel control problem for discrete systems 离散系统的最小燃料控制问题

By applying the dual space theory of linear vector spaces, the minimum l1 norm can be found by maximizing a linear functional with a l¿ norm constraint. This maximization enables the application of a linear programming technique which is usually very efficient. The control sequence which achieves the minimum fuel cost is then found by applying the alignment property in the dual space.","PeriodicalId":164707,"journal":{"name":"1975 IEEE Conference on Decision and Control including the 14th Symposium on Adaptive Processes","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126957436","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}

Three simplified cases are used to demonstrate this point. The cases technically are shown to be related to the kinds of analyses common in System Theory. From this it is argued that as economists move away from general equilibrium models under certainty with analysis by static equilibrium systems of simultaneous equations, the concepts and methods of systems science will become more important to the economist.","PeriodicalId":164707,"journal":{"name":"1975 IEEE Conference on Decision and Control including the 14th Symposium on Adaptive Processes","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121488817","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}
