DC Motor Rev. Sliding Mode Controller

Uses the method from my design DC Motor Revolution Detector http://everycircuit.com/circuit/6753368923176960 to read the motor revolutions / s. The dirivative of this result is used as feedback to control the acceleration of the motor. The acceleration is set discretely based on the following three conditions (modes): - Revolutions / s < reference: Acceleration = 2 - Revolutions / s ≈ reference: Acceleration = 0 - Revolutions / s > reference: Acceleration = - 2 * The span where rev. / s ≈ ref. is satisfied can be changed by changing the gain in the left most opamp coupling. * The two non-zero rates of acceleration can be changed individually with the two upper left voltage generators (2 V = 2000 rpm / s). * The controller used in the acceleration loop is a simple integrator. * Use the voltage generator next to the motor to set the rpm (1 V = 1000 rpm). The motor rev. detector circuit is scaled for a specifik motor voltage and start current, but besides these, the parameters can be changed at will. This is explained better in the design mentioned above.
