Our approach is simply to use a nonstationary \"potential-based reinforcement function\" for shaping the reinforcement signal given to the learning \"base-agent\". The base-agent employes SARSA(O) or adaptive asynchronous value iteration (VI), and the supervised inputs to the base-agent from the \"subagents\" involved with other parallel independent reinforcement learnings and if available, from experts are \"merged\" into the potential-based reinforcement function value and the value is put into the update equation of SARSA(O) for the Q-function estimate or of adaptive asynchronous VI for the optimal value function estimate.

Frequently, the emergency evacuation plan has to be modified due to uncertain data and the occurrence of an event. Therefore, the personnel inventory control and scheduling algorithms must be able to take into account uncertainty. In this work, this system is divided into inventories and jobs i.e., loading, unloading, and transportation, and the EPE problem is solved optimizing a transportation capacitated network which is coupled to a set of parallel plants (platforms), where each plant has two processes. In this system, the platforms are served using a dispatching rule, and the VR and dispatching is done solving a mixed-integer nonlinear programming problem (MINLP) each time an event occurs. This approach is illustrated with a case study of a six-vehicle, eight-platform, off-shore oil platform system. Although small, this case study preserves the main characteristics of a real complex since it includes different vehicle types (boats and helicopters), and different platform and vehicle capacities","PeriodicalId":265903,"journal":{"name":"2006 American Control Conference","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131426095","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}

We restrict our attention to systems which are passive with respect to the measured output, and the sensor disturbance has a finite discrete spectrum. A simple condition for zero-state detectability of passive partially linear systems is derived, and the result is employed to analyze the loop interconnection resulting from the application of internal model-based controllers to the perturbed plant. The analysis applies directly to the problem of stabilizing the angular velocity and/ or regulating the attitude of a rigid body using noisy angular rate measurements.

The method is applicable when two-position, electronically controlled valves are connected to each chamber of a gerotor motor or pump. For motors, the multi-level control can directly regulate the torque, similar to torque regulation of a DC electric motor through current control. For pumps, multi-level control can directly regulate the volume flow rate. Multi-level control permits the regulation of hydraulic motors and pumps without the energy loss associated with a flow control valve, or the mechanical complexity associated with a variable displacement device. Regulation is achieved by using computer control to exploit the complete set of valve combinations, creating torque or flow patterns that are not possible with mechanically actuated values","PeriodicalId":265903,"journal":{"name":"2006 American Control Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117124882","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 controllers do not cancel benign nonlinearities and can accommodate control saturation effects. Being intrinsic, we do not assume any coordinates. Finally, we illustrate our technique by explicitly deriving a control law that almost globally asymptotically stabilizes the inverted position of a spherical pendulum. Continuing this work by N. A.
