The block is a relay link with a deadband, at the output it generates a logical 1 or 0 according to the following algorithm:
where x1(t), x1(t) are the input signals of the block; y(t) is the output signal; a, ε0 is the value of the return zone and the threshold of actuation.
- two signals are sent to the input of the block, which are compared with each other;
- if their difference exceeds the threshold, the block generates a logical 1 at the output;
- if the difference between the first and second input becomes less than the threshold (taking into account the return zone), then the block generates a logical 0 at the output:
where x1(t), x1(t) are the input signals of the block; y(t) is the output signal; a, ε0 is the value of the return zone and the threshold of actuation.
The block is a submodel. To view the structure of the algorithm, right-click Actions → Enter to the submodel.
Inputs
- x1 - the first input signal;
- x2 - the second input signal.
Outputs
- output - the checkbox (flag) of exceeding the difference threshold.
Properties
- Threshold of actuation — the setpoint to which the difference in input signals is compared;
- Return zone — a value that is subtracted from the setpoint to form the lower switching limit.
Parameters
none
