I need some information on the AT89C52 based DC motor control for the antenne positioner system. Its feedback control circuit to drive the motor .
I will be gratful if some useful links can be provided with some circuit diagrams.

For DC motor control. H bridge is one, using PLL thats another option.
For switching look up for PWM, but you must be sure to correctly saturate the transistors.

I built a scheme that controls the speed of DC motor through the PC, see the circuit. Everything was fine with power supply of the motor up to 30V. When I applied 200V everything burned. I didn't understand what happened - the two MOSFETs IRFP260N, the MOSFET driver L6384 and the uC are out of order.
I didn't apply a load but this couldn't (...)

Speed control using resistors is not correct approach techincally because you are controlling voltage where as for DC motors you need to control current. So I think you should look for current control instead of voltage control(this is only AC motors).

To control the speed, PWM is the easy and efficient method. Here you can find a circuit and an example code for DC motor control with PIC16F877A, using PWM. While the program has been written for mikroC compiler, you should have no problem in "porting" it to CCS.

The most common form of relay based DC motor control is to use the relay to switch the motor contacts to control the direction the motor runs. Relays can also be used to control speed by switching contact between voltages to apply to the DC motor.
Hope this helps.
