<p>The VoltsHertzController component represents the controller logic for the variable speed drive. The volts hertz control is a simple and widely used method for controlling the speed of an AC induction motor by adjusting the voltage and frequency supplied to the motor at a constant ratio.</p>
152+
<p>The model has three inputs and two output connectors. The W_ref input connector represents the reference synchronous speed that is user defined,
153+
motor_speed input is the motor speed that is generated by the motor model, and the Vc input is the capacitor voltage value from the AC2DCandDC2AC component.
154+
The m output is the PWM modulation index, and the we output is the synchronous speed that is used in the controllable motor model.</p>
155+
<p>The modelling of such devices is based, mainly, on the following reference:</p>
156+

<p>The AC2DCandDC2AC component represents the power electronics component of the variable speed drive.
181+
The model provides an interface between two terminals. Terminal pin p is related to the grid bus side and terminal pin n is related to the
182+
motor terminal bus. The model is an average representation of the switching components of a real variable speed drive, thus being ideal for long simulation durations on phasor dynamic simulations.</p>
183+
<p>The model has one input and one output connectors. The m_input input connector represents the pwn modulation index, while the Vc output connector represents the capacitor voltage value used in the controller logic block.</p>
184+
<p>The modelling of such devices is based, mainly, on the following reference:</p>
