  2. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    This section describes the parallel or non-interacting form of the PID controller. For other forms please see § Alternative nomenclature and forms. The PID control scheme is named after its three correcting terms, whose sum constitutes the manipulated variable (MV). The proportional, integral, and derivative terms are summed to calculate the ...

    en.wikipedia.org/wiki/Project_Initiation...

    The project initiation documentation is a PRINCE2 [1] term representing the plan of approach in project management. It is assembled from a series of other documents, including the business case, the terms of reference, the communication plan, the risk register, the project tolerances, the project plan, and any specific project controls or inspections as part of a departmental quality plan or ...

    A Piping and Instrumentation Diagram (P&ID or PID) is a detailed diagram in the process industry which shows process equipment together with the instrumentation and control devices. It is also called as mechanical flow diagram (MFD).

    Any Euclidean norm is a Dedekind-Hasse norm; thus, (5) shows that a Euclidean domain is a PID. (4) compares to: (4) compares to: An integral domain is a UFD if and only if it is a GCD domain (i.e., a domain where every two elements have a greatest common divisor) satisfying the ascending chain condition on principal ideals.

  6. Setpoint (control system) - Wikipedia

    en.wikipedia.org/wiki/Setpoint_(control_system)

    In the context of PID controller, the setpoint represents the reference or goal for the controlled process variable. It serves as the benchmark against which the actual process variable (PV) is continuously compared.

    en.wikipedia.org/wiki/Structure_theorem_for...

    In mathematics, in the field of abstract algebra, the structure theorem for finitely generated modules over a principal ideal domain is a generalization of the fundamental theorem of finitely generated abelian groups and roughly states that finitely generated modules over a principal ideal domain (PID) can be uniquely decomposed in much the same way that integers have a prime factorization.
