I am planning to design a power wheelchair with touchpad control to help disable people,who have stroke,to control the wheelchair easily.Which microcontroller will be the best linking for touchpad control and power motor?
The one with which you have the most prior experience and most familiarity with the toolset.

Touch pads can be implemented from most micro processor I/O ports. There is a small ap note that covers touch switch basics on our website.
I agree with the other comment. Most small processors would work select the one you are familiar with.

Chose a device with HW support for CapSense - makes development easier, and the SW can focus on the filtering and user feedback..
Look at SiLabs C8051F70x series, for the User interface head unit, and use the SiLabs C8051F5xx Automotive family for the Motor Control. These are 5V operation, so can directly drive Power MOSFETS.
and also see their toolsticks.
Or Microchip or PSOC
Or AVR Or ARM Or MSP430 Or ad infinitum...
The clue is that there is no single "best" microcontroller *family* much less a particular entry in that family. If the original poster has experience with a given family, that's the place to start and iterate from there. If he's never used any microcontrollers at all, then, if it's a commercial venture, it's time to find somebody willing to contract for the work.
If it's a one-off for someone with no microcontroller experience, it's probably best to find a dev board that includes the full kit with compiler, debugger, IDE, programming interface, probably an on-board character LCD, and a bunch of I/O. Since "how big?" may be outside the OP's experience, I'd suggest springing for a too large ARM setup; better to have extra resources than to get halfway done and be resource constrained.
