Description

DRIVE FOR HOME APPLIANCE
FIELD OF THE INVENTION
The present invention relates to a drive for a home appliance, and, more specifically, to a drive controlled by a PID controller.
BACKGROUND OF THE INVENTION
Feedback or control loops are used to control many industrial processes, such as the rotational speed of motors. Simple control loops include a set point or desired value input, a measurement input which indicates the actual value of the parameter to be controlled, and a comparator to develop an error signal related to the difference between the desired and actual values. A control loop output signal, related to the error signal, is then applied to the control device whose parameter is to be controlled, such as a motor whose speed is to be controlled by the loop.
The control accuracy and response characteristics of control loops are conventionally enhanced by adding various control terms or weightings to the error signal in order to develop the control output signal. One classic enhanced servo control loop is known as the PID loop which includes proportional, integral and derivative terms added to the error signal to develop the desired control signal. PID loops are often applied where the accurate maintenance of a controlled parameter is important, such as the control of the rotational speed of the motor shaft in the drive of the home appliance.
According to the PID algorithm, a control signal i/(t) is described by:
Figure imgf000002_0001
where e is the control error defined as where y is a current value of a parameter
Figure imgf000002_0002
to be controlled and is a reference value or a requested value of the aforesaid parameter. The reference variable is often called the set point. The control signal is thus a sum of three terms: the P-term (which is proportional to the error), the I-term (which is proportional to the integral of the error), and the D-term (which is proportional to the derivative of the error). The controller parameters are proportional gain K, integral time T1, and derivative time TD.
Referring to Fig. 1 , a system 10 comprises a regulating element 20 providing a preset signal ysp (reference variable) corresponding to a parameter of a plant 80 to be controlled. The plant 80 is provided with a sensor configured for transmitting a signal corresponding to a real time value y of the parameter to be controlled. A summator 30 calculates a value of the control error e provided to units 40, 50 and 60 which are proportional, integral and derivative unit, respectively. Applications of the PID controller to different tasks are characterized by different values of the proportional gain K, integral time T1, and derivative time To.
A problem of maintaining stable rotational speed relates to substantially long processing time and can be implemented by means a high-speed CPU which is very expensive in terms of home appliance costs. Cheaper 8-bit or 16-bit CPUs have slower responsiveness and provide unstable control quality resulting in fluctuations of rotational speed.
There is a long-felt and unmet need to provide a cheap drive for a home appliance. The aforesaid drive should be controlled by a cheap fast PID controller providing stable rotational speed of the drive independently on shaft load.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
The following description is provided, so as to enable any person skilled in the art to make use of said invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifications, however, are adapted to remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically to provide a drive for a home appliance and a method of actuating the same.
Reference is now made to Fig. 2, presenting a drive for a home appliance 100 comprising a mode selector providing a signal (preset signal) corresponding to a target rotational speed of an electric motor 350 connectable to an operating tool of the home appliance (not shown). AC and DC electric motors are in the scope of the present invention. The motor 150 is energized by a voltage corresponding to a target rotating speed at idle. Then, the voltage on the motor is controlled by a PID controller 120. A feedback is formed by a Hall sensor 140, a summator 115, PID controller 120 and regulating element 130 (for example, a triac). Specifically, an electric signal corresponding to a real time value of rotational speed is transmitted to the summator 1 15 which computes a value of an error (deviation from the target speed). Then, the error signal is divided into 3 channels providing proportional, integi'al and derivative processing of the error signal. Output signals from the aforesaid channels are summated and a resultant signal
Figure imgf000006_0005
is transmitted to the element 130 which controls the voltage on the motor 150.
According to the present invention, is computed according to the following equation:
Figure imgf000006_0003
where is a present sample
Figure imgf000006_0006
is a previous sample,
Figure imgf000006_0004
is a last previous sample; X is in a range between 1 .5 and 2, Y between 1 and 3, Z between 1 and 3.
The values X, Y and Z are defined as follows:
Figure imgf000006_0001
and
Figure imgf000006_0002
The gains of the PID controller 120 are preset. In exemplar manner, Table presents specific operational modes of the drive for a home appliance.
Table
Figure imgf000006_0007
According to the present invention, the PID controller is tuned by presetting proportional, integral and derivative gains. Explicitly, preset gain values are given the following equations:
Figure imgf000007_0001
; and
Figure imgf000007_0002
Figure imgf000007_0003
It should be emphasized that a most advantage of the disclosed technical solution is presetting (preliminary tuning) of the drive 100 according to a specific home appliance to be connected to the drive. The following home appliances are connectabie to the drive of the present invention:
1. Stand mixer;
2. Table blender,
3. Food processor,
4. Soup maker,
5. Hand mixer,
6. Juicer,
7. Hand blender,
8. Power tool and
9. Any combination thereof.
Keeping the values X, Y and Z provides speedling the PID controller. According to experimentally obtained data, an 8-digit PID controller having gains preset according to the present invention is able to process 100 sample data per second, vvliile performance of a conventional PID controller is characterized by processing of about 10 sample data per second.
Reference is now made to Fig, 3, presenting exemplar electric circuit diagram of a drive for a home appliance. The PID controller is implemented in microcontroller SOP 14-7. A universal electric motor is connected to the electric grid via a triac BTA316. Hall sensor provides an error signal to the PID controller which in transmits control voltage to the triac which regulates voltage on the electric motor of the drive.
It should be appreciated that the PID controller with preset proportional, integral and derivative gains as described above keeps rotating speed of the home appliance drive substantially independent on a drive load.
