Can anyone please suggest a way of performing regenerative braking of dc motor without using sim power systems in matlab?
I understand that we need to implement using a rectifier kind of circuit but can we do without using it??
 

During regenerative braking the motor is acting as a generator, so the energy must be absorbed by a load resistor. The problem is that when the motor is being powered the load will take power as well, so what is required is a switch that puts the load on the motor when the supply is off. The easiest way is to use a relay whose coil is connected to the original motor supply. The actual supply goes through the relay when the coil is energised and when the coil is de-energised the load goes to the motor.

A high current capable boost converter is what you want.
It will run differently than a normal fixed output, slightly
variable input - you need a wide range of input from the
full speed armature voltage, to as low a RPM's back EMF
as you can manage, so that your braking recoups as much
kinetic energy as possible. And your braking effort needs
to be pedal-responsive, yet also not push more current
than the battery / superdupercapacitor / whatever can
accept (or, a backstop dissipator might be engaged if
braking demand exceeds battery charge-accept limits).

Matlab is only a means of modeling it.
