On generalized terminal state constraints for model predictive control
This manuscript contains technical results related to a particular approach
for the design of Model Predictive Control (MPC) laws. The approach, named
"generalized" terminal state constraint, induces the recursive feasibility of
the underlying optimization problem and recursive satisfaction of state and
input constraints, and it can be used for both tracking MPC (i.e. when the
objective is to track a given steady state) and economic MPC (i.e. when the
objective is to minimize a cost function which does not necessarily attains its
minimum at a steady state). It is shown that the proposed technique provides,
in general, a larger feasibility set with respect to existing approaches, given
the same computational complexity. Moreover, a new receding horizon strategy is
introduced, exploiting the generalized terminal state constraint. Under mild
assumptions, the new strategy is guaranteed to converge in finite time, with
arbitrarily good accuracy, to an MPC law with an optimally-chosen terminal
state constraint, while still enjoying a larger feasibility set. The features
of the new technique are illustrated by three examples.Comment: Part of the material in this manuscript is contained in a paper

On reduction of differential inclusions and Lyapunov stability
In this paper, locally Lipschitz, regular functions are utilized to identify
and remove infeasible directions from set-valued maps that define differential
inclusions. The resulting reduced set-valued map is point-wise smaller (in the
sense of set containment) than the original set-valued map. The corresponding
reduced differential inclusion, defined by the reduced set-valued map, is
utilized to develop a generalized notion of a derivative for locally Lipschitz
candidate Lyapunov functions in the direction(s) of a set-valued map. The
developed generalized derivative yields less conservative statements of
Lyapunov stability theorems, invariance theorems, invariance-like results, and
Matrosov theorems for differential inclusions. Included illustrative examples
demonstrate the utility of the developed theory
Staffing the CMC for Success
Librarians, paraprofessionals, and student workers employed in the
curriculum materials center (CMC) require specialized skills to assist
preservice and in-service teachers and faculty. As technology continues
to drive changes in services, CMC staffing plays a vital role in delivering
new technology-driven services while maintaining traditional ones.
This chapter discusses the development of a CMC staff whose members
possess unique skills necessary to deliver services successfully based upon
the following factors: determining staffing needs, reviewing existing staffing
patterns, creating new job descriptions and competencies for future
services, developing a long-range staffing plan, hiring technology- and
team-driven staff, retaining staff, utilizing performance evaluation as an
effective staffing tool, and valuing the CMC staff
CONSERVATION AND NATURAL RESOURCES Hazardous Waste Management: Provide for Direct State Government Operation and Management of Hazardous Waste Facilities
The Act amends the Georgia Hazardous Waste Management Authority Act by including within the definition of project the renovation of an existing waste treatment or disposal facility that provides for the treatment, storage, or disposal of any solid waste requiring special handling. The Act also adds a new provision which would permit the Department of Industry and Trade to plan, own, and operate a hazardous waste facility and to charge a fee for the use of such state facility. Additionally, the Act provides partial immunity from liability to members, officers, and employees of the Georgia Hazardous Waste Management Authority
CONSERVATION AND NATURAL RESOURCES Plant Disease, Pest Control, and Pesticides: Limit Liability of Farmers
The Act establishes a negligence standard for farmers who pollute the land, waters, air, or other resources of the state through application or use of fertilizers, plant growth regulators, or pesticides
