Abstract
Abstract The regulator having a P-member and an I-member uses a timing means to delay the desired value signal prior to subtraction of the delayed signal from the received actual value signal. The resultant signal is then delivered to the I-member. A further P-member is also used to receive the desired value signal and to deliver the signal for addition to the superimposed signals from the first-named P-member and I-member in order to produce a load-control signal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
An output regulator for a thermal power-producing plant comprising a pair of inputs; an output for emitting a load control signal; a first P-member connected to one of said inputs to receive an actual value signal; an I-member connected to said one input to receive said actual value signal; a second P-member connected to the other input of said inputs to receive a desired value signal, said second P-member having a smaller transmission factor than said first p-member; a timing means connected to said other input for receiving and delaying said desired value signal, said timing means being connected to said I-member to emit the delayed desired value signal to said I-member; an addition means connected to said first P-member and said I-member to receive superimposed signals therefrom, said second P-member being connected to said addition means to deliver said desired value signal to said addition means for addition to said superimposed signals to produce the load control signal in response thereof, said addition means being connected to said output to deliver the load control signal thereto.
Claim 2
Dependent Claim
177 words
An output regulator for a thermal power-producing plant comprising a pair of inputs; an output for emitting a load control signal; a first P-member connected to one of said inputs to receive an actual value signal; an I-member connected to said one input to receive said actual value signal; a second P-member connected to the other input of said inputs to receive a desired value signal, said second P-member having a smaller transmission factor than said first p-member; a timing means connected to said other input for receiving and delaying said desired value signal, said timing means being connected to said I-member to emit the delayed desired value signal to said I-member; an addition means connected to said first P-member and said I-member to receive superimposed signals therefrom, said second P-member being connected to said addition means to deliver said desired value signal to said addition means for addition to said superimposed signals to produce the load control signal in response thereof, said addition means being connected to said output to deliver the load control signal thereto.
Claim 3
Dependent Claim
20 words
An output regulator as set forth in claim 1 wherein at least one of said P-members also has a D-character.
Claim 4
Dependent Claim
15 words
An output regulator as set forth in claim 2 wherein said timing means is adjustable.
Claim 5
Dependent Claim
15 words
An output regulator as set forth in claim 1 wherein said timing means is adjustable.
Claim 6
Dependent Claim
158 words
An output regulator for a thermal power-producing plant comprising a pair of inputs and an output; a first P-member connected to one of said inputs to receive an actual value signal therefrom; a second P-member connected to the other of said inputs to receive a desired value signal therefrom; a timing means connected to said other input to receive and delay said desired value signal; a comparison means connected to said one input and said timing means to subtract the delayed desired value signal from the actual value signal to produce a resultant signal; an I-member connected to said comparison means to receive the resultant signal; a first addition means connected to said first P-member and said I-member to superimpose signals received therefrom; and a second addition means connected to said first addition means and said second P-member to add said superimposed signals and said desired value signal to produce a load-control signal for delivery to said output.
Claim 7
Dependent Claim
158 words
An output regulator for a thermal power-producing plant comprising a pair of inputs and an output; a first P-member connected to one of said inputs to receive an actual value signal therefrom; a second P-member connected to the other of said inputs to receive a desired value signal therefrom; a timing means connected to said other input to receive and delay said desired value signal; a comparison means connected to said one input and said timing means to subtract the delayed desired value signal from the actual value signal to produce a resultant signal; an I-member connected to said comparison means to receive the resultant signal; a first addition means connected to said first P-member and said I-member to superimpose signals received therefrom; and a second addition means connected to said first addition means and said second P-member to add said superimposed signals and said desired value signal to produce a load-control signal for delivery to said output.
